Question

The double number line shows the approximate number of ounces in a certain number of pounds:

Based on the number line, about how many ounces are there in 8 pounds?

A) 128 ounces
B) 144 ounces
C) 160 ounces
D) 176 ounces

Answer 1

Hi there! 8 pounds equals 128 ounces. Answer A is correct.

In the number line we can see that 5.5 pounds equals 88 ounces.

Next we can find out the value of 1 pound by dividing by 5.5.
88 / 5.5 = 16
Therefore one pound equals 16 ounces.

Finally we need to multiply the value of 1 pound by 8 to find the value of 8 pounds.
16 × 8 = 128

Now we have our answer: 8 pounds equals 128 ounces. Answer A is correct.
