Answer:
We need 4/5 cups of oil
Step-by-step explanation:
We can use ratios to solve. Put the amount of oil over the number of batches
2/3 cup x cups
---------------- = --------------
2.5 batches 3 batches
Using cross products
2/3 * 3 = 2.5 *x
2 = 2.5 x
Divide each side by 2.5
2/2.5 = 2.5x/2.5
.8 =x
Changing this back to a fraction
4/5 =x
We need 4/5 cups of oil
