Comparing Ratios Using Fractions

Compare 4:10 and 12:20 using fractions. Which ratio is
smaller? How do you know?

Answer 1

4:10

Explanation:

First, I wrote each ratio as a fraction. Then I found a common denominator of 20. The fraction 4/10 is 8/20. Comparing numerators, 8 is less than 12, so the ratio 4:10 is smaller.

Answer 2

4:10

Explanation:

4:10 = 4/10 = 2/5

12:20 = 12/20 = 6/10 = 3/5.

So 4:10 is smaller than 12:20 because 2/5 is less than 3/5.
