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