Question

Kai bought 3 1/8 pounds of ground beef, 1 3/4

pounds of sausage, and some ground turkey for a chili cook-off. He bought 6 pounds of meat total. How much ground turkey did he buy?

A. 1 1/2 pounds

B. 1 1/8 pounds

C. 4 1/2 pounds

D. 4 7/8 pounds

Answer 1

B. 1 1/8 pounds.

Explanation:

Let the weight of turkey he bought be x pounds.

Then we have the equation:

x + 3 1/8 + 1 3/4 = 6

x = 6 - 3 1/8 - 1/ 3/4

Converting to improper fractions

x = 6 - 25/8 - 7/4

We could use a calculator to do this but it also can be done manually by converting all amounts to fractions with denominator 8:

x = 48/8 - 25/8 - 14/8

= 9/8

= 1 1/8 pounds.

Answer 2

B. 1 1/8 pounds

Explanation:

What we know:

6 Pounds of meat in total

3 1/8 pounds of ground beef

1 3/4 pounds of sausage

Combining the pounds of ground beef and sausage together:

3 1/8 + 1 3/4 = 4 7/8

In all he has 6 pounds of meat. He we know the combined weight of the ground beef and sausage combined: 4 7/8 pounds. Therefore, the equation is...

6 - 4 7/8 =

The answer is...

B. 1 1/8 pounds
