The document provides instructions for finding the least common multiple (LCM) of two numbers. It defines key terms like multiple, common multiple, and least common multiple. It explains how to find the common multiples of two numbers by listing out their individual multiples and seeing which numbers are shared between the lists. It also introduces using prime factorizations to calculate the LCM by finding the common prime factors between the two numbers and multiplying all of the factors.
Fractions, decimals, and percentages
This document provides an overview of fractions, decimals, and percentages. It explains how to convert between the different representations and compare their values. Key points covered include:
- Fractions represent a part over a whole
- To convert a fraction to a percentage, express it with a denominator of 100
- To convert a percentage to a fraction, write it as a fraction over 100
- To write a decimal as a percentage, multiply it by 100 and add the percent sign

Ratios part/part and part/whole
Here are the key points about ratios:
- A ratio expresses the relationship between two quantities. It can be written as A:B, A/B, or "A to B".
- "Per" and "for every" indicate a ratio. For example, "2 miles per hour" means the ratio of miles to hours is 2:1.
- Part to part (P/P) ratios compare two parts of a whole, like the ratio of girls to boys. Part to whole (P/W) ratios compare a part to the whole, like the ratio of girls to total students.
- P/W ratios can be thought of as fractions because they relate a part to the whole. P

Pyramid Printing Company publishes magazines, catalogs, and retail.docx
Pyramid Printing Company publishes magazines, catalogs, and retail inserts for distribution in large metropolitan-area newspapers. Its largest customer is the New York News Company, for which Pyramid prints sales fliers and coupon inserts.
Pyramid has contractual agreements with its customers; its present pricing strategy is cost-plus, and customers also agree to a yearly price escalation based on inflation. Pyramid completes the escalation based on cost-of-operations increases.
Recently, Obelisk Publishing proposed a bid to the New York News Company for alternative pricing to counter Pyramid Printing’s contract, which will be up for renewal. To compete with the bid from Obelisk, Pyramid will have to employ target costing.
For this discussion:
· What are the differences between cost-plus and target-costing approaches to developing appropriate pricing? Give advantages and disadvantages of each.
· Are there elements of the value chain that Pyramid may leverage in order to optimize target costing for a mature customer relationship?
