Answer: 8 pounds.
Step-by-step explanation:
1) Let's start making clear the statement it is: " Mama Mia restaurant used 1/2 of their mozzarella cheese making pizza and the remaining 64 ounces making pasta. How many pounds of mozzarella cheese did Mama Mia start with? 1 pound = 16 ounces."
2) Since, 1/2 of the chesse was used to make pizza, the remaining part, which was used to make pasta, is 1 - 1/2 = 1/2.
3) Hence, you say that 1/2 of cheese equals 64 ounces, which means that Mama Mia started with 2 × 64 ounces, i.e. 128 ounces.
4) Now, use the conversion factor to convert 128 ounces to pound:
a) 1 pound = 16 ounces ⇒ 1 = 1 pound / 16 ounces
b) 128 ounces × 1 pound / 16 ounces = 8 pounds.
