Question

Zenin’s baby sister weighed 132 ounces at birth. How much did his sister weigh in pounds and ounces?

Answer 1

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

`(1pound)/(16ounces)`=`(x pounds)/(132 ounces)`

Cross multiply this:

`(1pound*132ounces)=(16ounces*xpounds)`

`132 = 16x`

Isolate x by dividing both sides by 16

`132/16=(16x)/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*16=4`

So the answer is 8 pounds and 4 ounces.

Answer 2

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.
