Using a commen denominator to order fractions

Answer 1

68 /100 ad 65/100 so 17/26 is greater than 13/20

Answer 2

The common denominator is 100. There is a mathematical way to solve for it, but in this case, guess and check for the common denominator works well.

so 17/25, when multiplied by 5/5 comes out as 75/100
13/20 multiplied by 4/4 is 42/100

so 17/25 is larger
