Question

Which proportion would you set up to change 5 pounds to ounces?

A: 1/16 = 5/x
B: 1/8=5/x
C: 1/8=x/5
D: 1/16=x/5

Answer 1

• We know 1lbs=16oz

Hence

• 1oz=1/16

The proportion is

• 1/16=5/x

Option A

solve for x.

• x=16(5)
• x=80oz

Answer 2

A: 1/16 = 5/x

Explanation:

1 pound is 16 ounces

5 pounds is 80 ounces

let 5 pounds be x

the equation should be x = 80

A: 1/16 = 5/x

x=80

B: 1/8=5/x

x=40

C: 1/8=x/5

`x=(5)/(8)`

D: 1/16=x/5

`x=(5)/(16)`
