Mouse a ran through a maze in 2 1/8 minutes mouse b ran the same same maze in 1 5/6 minutes how much longer did it take mouse a

The answer is 7/24. It took Mouse A 7/24 more minutes than Mouse B to complete the maze. Both fractions have a common denominator of 24. Since for Mouse A the denominator is 8, you multiply the numerator by 3, since 8 times 3 equals 24. You get the answer 3/24. For Mouse B, the denominator is 6, so you would multiply the numerator by 4, since 6 times 4 equals 24. You get the answer of 20/24. From 20/24, you count until you hit 3/24, knowing you start over at 1 right after you hit 24. (21, 22, 23, 24, 1, 2, 3). There are seven numbers in the parenthesis and you got your answer of 7/24.
