Answer:
15 pounds of onions are needed in the recipe.
Step-by-step explanation:
Total gallon of chopped onion needed for the recipe = 1 1/2 gallons
Solving the mixed fraction, we get
So, the chopped onion needed = 1.5 gallons
Also, 1 gallon = 160 ounces
So, 1.5 gallon = 1.5 x (160) ounces = 240 ounces
⇒ 1.5 gallon = 240 ounces
Now, 1 ounce = 0.0625 pounds
⇒ 240 ounces = 240 x 0.0625 pounds = 15 pounds
Hence, 15 pounds of onions are needed in the recipe.
