PROPORTION AND PERCENT OVERVIEW - MATEMATIKO
How to Solve Simple Proportions We use the attribute of proportions that the products of cross multiplication are equal Notice the example on the previous page: 3 2 6 4 = Notice that by cross multiplying: 6 X 2 12 4 X 3 12 = = We can use this attribute to solve simple proportions Remember that division is the opposite of multiplication

Ratios, Proportions, and Percent Applications
Ratios, Proportions, and Percent Applications The use of proportional thinking is a very important problem solving strategy, and it is at the core of many important mathematical concepts including slope, speed, percent, probability, similarity, scaling, direct and inverse variations, and trigonometric ratios
National Center for Health Statistics Data Presentation
Presentation Standards for Proportions Proportions (usually multiplied by 100 and expressed as percentages) are the most commonly reported estimates in NCHS reports For many NCHS reports, an automated rule is needed to determine whether or not estimates are sufficiently stable for publication The multistep NCHS Data Presentation
Statistical Analysis of Proportions
To understand statistical methods for analyzing proportions, we will take our rst foray into probability theory Proportions Case Studies Generalization 9 / 84 Bar Graphs Proportions are fairly simple statistics, but bar graphs can help one to visualize and compare proportions The following graph shows the relative number of individuals in each
Solving Percent Problems Using Proportional Reasoning
Students apply proportions to solve problems that involve percents Common Misconceptions Students will incorrectly set up the proportions by always putting the variable as the numerator in the second ratio or over 100 Students may multiply numerators and then multiply denominators instead of using cross products to solve the proportion
