Equivalent Ratios | MathHelp.com

Показать описание

This lesson covers equivalent ratios. Students learn to find equal ratios by first writing the given ratio as a fraction, then multiplying the numerator and denominator of the fraction by the same number. For example, to find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7. Next, multiply both the numerator and denominator of 1/7 by 2, to get 2/14, or 2:14, and multiply the numerator and denominator of 1/7 by 3, to get 3/21, or 3:21. So 2:14 and 3:21 are two ratios that are equal to 1:7. Students are also asked to determine whether two given ratios are equal, by first writing each ratio as a fraction, then writing each fraction in lowest terms. If the two fractions are the same when written in lowest terms, then the ratios are equal.

TO make sure you got it down, I usually replace all numbers with 9. But with this method, I would not recommend that if you want a challenge. For example. 3 digit numbers x 3 digit numbers with all nines would be 999 x 999. Just a way to make sure you get how to do a math example
