While researching universities, Mahtab learns that a typical class at Summerfield Technical University has 12 men and 6 women, and a typical class at Grant County University has 10 men and 7 women. Which university has classes with a higher ratio of men to women





Answer: 1


SOLUTION 1 :

 

Solve:

The ratio of men to women in a typical class at Summerfield Technical University is 12 to 6. At Grant County University, it is 10 to 7.

 We want to figure out which ratio is higher:

126 or 107


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

First write the ratio 126 as a decimal. Then convert the decimal to a percentage.

126 = 2.0000 = 200 %

Do the same thing for 107

107  = 1.4286 = 142.86 %


Now compare the percentages.

200 % 142.86 %

142.86 % is smaller than 200 %
