1 like•397 views
To multiply decimals, you multiply the numbers as whole numbers and then count decimal places to determine where to place the decimal point in the answer. For the multiplication 1.3 x 3, you multiply 3 x 3 = 9 and 3 x 1 = 3, writing 39 without regard to decimals. Since there is one decimal place in the original numbers, the decimal point goes after the first digit in the answer, making 3.9.

Percents, Decimals, And Fractions
Percents, decimals, and fractions can all be used to compare parts of a whole. There are two methods shown for writing decimals as percents: 1) using place value and proportions, or 2) more simply moving the decimal point two places to the right and multiplying by 100. Writing a fraction as a percent involves setting up a proportion with the fraction over the whole on one side and the unknown percent over 100 on the other side, then cross-multiplying and solving for the unknown percent value.

decimals. .pptx
Decimal numbers have a dot that separates the whole numbers from the fractional or partial numbers. There are several key operations for decimals: comparing decimals involves looking at the same place value; rounding decimals involves dropping digits and increasing or keeping the last digit as appropriate; adding and subtracting decimals involves lining up the decimals; multiplying decimals involves multiplying the numbers and counting total decimal places in the factors; and dividing decimals uses moving the decimals to represent division of whole numbers, with remainders requiring annexing zeros. Repeating decimals occur when the division has a non-terminating repeating portion.

This presentation was provided by Steph Pollock of The American Psychological Association’s Journals Program, and Damita Snow, of The American Society of Civil Engineers (ASCE), for the initial session of NISO's 2024 Training Series "DEIA in the Scholarly Landscape." Session One: 'Setting Expectations: a DEIA Primer,' was held June 6, 2024.A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Assessment and Planning in Educational technology.pptx
In an education system, it is understood that assessment is only for the students, but on the other hand, the Assessment of teachers is also an important aspect of the education system that ensures teachers are providing high-quality instruction to students. The assessment process can be used to provide feedback and support for professional development, to inform decisions about teacher retention or promotion, or to evaluate teacher effectiveness for accountability purposes.
