Examples are provided for finding the sum of fractions by keeping the denominator the same or finding the least common denominator.
Equivalent fraction
Equivalent fractions have the same value even though they may look different. They have different numerators and denominators because multiplying or dividing both the top and bottom of a fraction by the same number keeps its value. There are two ways to find equivalent fractions: 1) multiply the numerator and denominator by the same number, or 2) divide the numerator and denominator by the same number.
Subtracting similar fractions

The document ends with a short quiz assessing understanding of multiplying mixed numbers.
Adding similar fractions
Fraction represents equal parts of a whole. A fraction consists of a numerator and denominator. To add similar fractions, you must make sure the denominators are the same. Then you add the numerators and put the sum over the original denominator. Finally, simplify the sum if possible. Examples are provided where the fractions 1/3 + 1/3 = 2/3, 2/5 + 1/5 = 3/5, and 3/5 + 2/5 = 1.

Ppt addition of dissimilar fractions (loids)
This document provides instructions on how to add dissimilar fractions. It begins by listing examples of finding the least common denominator of sets of fractions. It then works through an example problem of adding 1/2 kg of lanzones and 1/4 kg of grapes. The key steps are to first find the least common denominator to make the fractions similar, then add the numerators and keep the same denominator. Finally, it lists three practice problems for the student to solve.
GREATEST COMMON FACTOR AND LEAST COMMON MULTIPLE
1) Greatest common factors (GCF) and least common multiples (LCM) are important concepts in mathematics. The GCF is the largest integer that divides two or more numbers, while the LCM is the smallest integer that is a multiple of two or more numbers.
2) There are several methods to find the GCF and LCM, including listing factors, using a factor tree, and continuous division. These methods involve breaking numbers down into their prime factors to identify common factors or multiples.
3) For the example of finding the GCF and LCM of 36 and 48, the GCF is 12 and the LCM is 144 using either the factor tree or continuous division methods.
Fractions comparing ordering
This document discusses comparing and ordering fractions. It provides examples of using less than, greater than, and equal to symbols to compare fractions with different denominators. It explains that to do this, you need to find the least common denominator and rewrite the fractions with equivalent denominators. The document also gives examples of ordering fractions from least to greatest value by finding a common denominator and comparing the numerators.
Division
Division is one of the four basic mathematical operations. It involves splitting a number, called the dividend, into equal groups or parts using another number, called the divisor, to find the quotient. There are two forms of writing division - horizontal uses the division symbol ÷, while vertical stacks the dividend above the divisor with the answer below. Division is the opposite of multiplication, so if you know a multiplication fact you can derive the corresponding division fact.
Addition of fractions
1) A fraction represents a part of a whole. Adding fractions is different than adding whole numbers. There are two types of fraction addition problems: those where the fractions have the same denominator, and those where the fractions have different denominators.
2) For problems where the fractions have the same denominator, you simply add the numerators and keep the same denominator.
3) For problems where the fractions have different denominators, you find the least common multiple of the denominators and convert the fractions to equivalent fractions with that denominator before adding the numerators and keeping the common denominator.
Dividing decimals part 1
This document provides instructions and examples for dividing decimals. It explains that when dividing a decimal by a whole number, the decimal point is placed in the quotient directly above the decimal point in the dividend. It also explains that when dividing decimals, the decimal point in the divisor is moved to the right until the end of its digits, and the decimal point in the dividend is moved the same number of places. This is demonstrated through examples of dividing decimals by whole numbers and decimals.
Adding and Subtracting Fractions with Like Denominators
The document discusses adding and subtracting fractions with like denominators. It explains that fractions have like denominators if they have the same number on the bottom. To add fractions with like denominators, you add the top numbers and keep the bottom number the same. To subtract fractions with like denominators, you follow the same steps as addition but subtract the top numbers instead of adding them. Examples are provided to demonstrate both addition and subtraction of fractions with like denominators.

Geometric Construction: Creating a Teardrop Shape
Constructing a teardrop shape involves drawing three circles of different radii using a compass on graph paper. The teardrop shape is formed by the overlapping circular arcs from a radius 5 circle, another radius 5 circle, and a radius 3 circle. The overlapping arcs are highlighted and isolated by erasing the remaining circular areas to reveal the smooth teardrop curve created by the intersecting arcs.

Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered
- Reducing license cost by finding and fixing misconfigurations and superfluous accounts
- How do CCB and CCX licenses really work?
- Understanding the DLAU tool and how to best utilize it
- Tips for common problem areas, like team mailboxes, functional/test users, etc
- Practical examples and best practices to implement right away

The meet-up will be hosted by Eindhoven University of Technology (TU/e), a research university specializing in engineering science & technology.
Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.
