Jack brought 2 quart of motor oil. His car took 1quart and another half quart. How many cups of oil does he have left?
1 quart = 4 cups
2 - 1 1/2 = 1/2
How many cups in half a quart?
four
To solve this problem, you need to convert quarts to cups. Here's how you can do it:
First, recall that 1 quart is equal to 4 cups.
So, Jack initially had 2 quarts of motor oil, which is equivalent to 2 x 4 = 8 cups of oil.
His car took 1 quart, which is equal to 1 x 4 = 4 cups of oil.
His car also took another half quart, which is equal to 0.5 x 4 = 2 cups of oil.
Therefore, the total amount of oil his car used is 4 + 2 = 6 cups.
To find out how many cups of oil Jack has left, subtract the amount used from the initial amount:
8 - 6 = 2 cups of oil.
So, Jack has 2 cups of oil left.
