Frequently Asked Questions
A proportion is an equation that states two ratios are equal. It expresses the relationship between four quantities where the ratio of the first pair equals the ratio of the second pair.
To solve proportion problems, use cross-multiplication. If a/b = c/d, then a×d = b×c. This allows you to find any missing value when the other three are known.
Proportions are used in cooking (recipe scaling), photography (aspect ratios), construction (blueprint scaling), finance (interest calculations), and many other everyday situations.
A ratio compares two quantities, while a proportion is an equation that states two ratios are equal. All proportions involve ratios, but not all ratios form proportions.
Yes, percentages are essentially proportions where one term is 100. For example, finding what percentage 25 is of 80 involves the proportion 25/80 = x/100.
