the automobiles. The first automobile holds 2 1/16 the seconds holds 3 1/8 quarts, and the third holds 4 1/2 quarts. How much total oil is used?

the total amount of oil used is 9 11/16 quarts

Step-by-step explanation:

in order to solve this question and find the total amount of oil used, you have to add all three of the mixed numbers.

1 - add all the whole numbers

3 + 2 + 4 = 9

2 - add all the fractions (denominator must be the same, convert if needed)

1/16 + 1/8 = 3/16

3/16 + 1/2 = 11/16

3 - combine the two results together

9 + 11/16 = 9 11/16
