Some people differentiate and say that the two quantities in a ratio have to have a same unit; some people don't The following proportion is read as "twenty is to twenty-five as four is to five. Also, two fractions a b and c d are proportional (a b = c Proportion, on the other hand, states that two ratios are equal. A ratio, which is a comparison of two numbers by division, is the quotient A comparison of two quantities by division is called a ratio and the equality of two ratios is called proportion. 11 Apply and use linear equations and/or inequalities as mathematical representations of proportional relationships to solve problem; including rate Let's talk about ratios and proportions.
