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

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

$1\frac{1}{2} = 1 + \frac{1}{2} = 1 + 0.5 = 1.5$

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.
