Answer: 1


SOLUTION 1 :

 

Solve:

Among 15-year-olds, the ratio of black belts to brown belts is 5 to 7. Among 16-year-olds, the ratio is 4 to 8.

 

We want to figure out which ratio is higher:

57 or 48


We can compare the ratios more easily if we express them as percentages.

First write the ratio 57 as a decimal. Then convert the decimal to a percentage.

57 = 0.71 = 71 %

Do the same thing for 48

48  = 0.50 = 50 %


Now compare the percentages.

71 % 50 %

50 % is smaller than 71 %

The 16-year-olds have a lower ratio of black belts to brown belts.
