So, if one were to express "the ratio of men to women", then the ratio, in English words, would be "15 men to 20 women" or just "15 to 20". Conversion factors are simplified ratios, so they might be covered around the same time that you're studying ratios and proportions.
Express the following ratio in simplest form: miles to 8 gallons The terms in this ratio have different units, so they won't cancel off; there will be units on my simplified ratio. That is the ratio -- the relationship -- of 15 to 5.
If both A and B are fractions and have like denominators, multiply both fractions by the denominator to eliminate it and you are left with two whole numbers If both A and B are fractions and have unlike denominators, find the LCD A, B and rewrite the fractions with the LCD as the denominator.
The ratio 3 : 8 is already simplified.
The units aren't factors, exactly, but they'll cancel in the same manner as do factors. Each number says its name.
