To find how many times the length of Noah's ride is compared to Mal's, you would divide the two mixed numbers:
6 3/4 divided by 4 1/2
Convert the mixed numbers to improper fractions:
27/4 divided by 9/2
To solve, multiply 27/4 by the reciprocal of 9/2:
27/4 * 2/9 = 3/2 or 1 and 1/2
So Mal's ride is 1.5 times longer than Noah's.
