Question

A recipe calls for 1 1/2 gallons of chopped onions.How many pounds of onions should you use if one cup of chopped onions weigh 6.5 ounces?

Answer 1

15 pounds of onions are needed in the recipe.

Explanation:

Total gallon of chopped onion needed for the recipe = 1 1/2 gallons

Solving the mixed fraction, we get

`1(1)/(2)  = 1 + (1)/(2)  = 1 + 0.5 = 1.5`

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.
