8 pounds and 4 ounces

#### Explanation:

If 1 pound = 16 ounces, we want to find how many pounds are in 132 ounces first.

so:

x being the unknown number of pounds

$\frac{1 p o u n d}{16 o u n c e s}$=$\frac{x p o u n \mathrm{ds}}{132 o u n c e s}$

Cross multiply this:

$\left(1 p o u n d \cdot 132 o u n c e s\right) = \left(16 o u n c e s \cdot x p o u n \mathrm{ds}\right)$

$132 = 16 x$

Isolate x by dividing both sides by 16

$\frac{132}{16} = \frac{16 x}{16}$

$8.25 = x$

We see that the answer is 8.25 pounds, but since it wants it in pounds and ounces, we can see the whole number 8 is pounds. To find the ounces, we multiply the 0.25 by 16. (Note: 1 pound is 16 ounces, thus we multiply it by 16.)

$0.25 \cdot 16 = 4$

So the answer is 8 pounds and 4 ounces.

Easy..

Step 1: Divide 132/16 because 1 pound= 16 ounces LEAVE YOUR ANSWER WITH THE REMAINDER!

Step 2: Your answer is the number of pounds while your remainder is the number of ounces.

132/16= 8 R4

So...
132 ounces = 8 pounds, 4 ounces.
