Question

you have a peice of yarn that's 12 1/2 ft long. you need to cut it into strips that are 1 1/4 ft long. how many strips will you have?

Answer 1

10

Explanation:

Let's make this into a decimal.

12 1/2=12.5

1 1/4=1.25

The number is same, except the decimal points.

To multiply a decimal by 10, you put the decimal point to the right.

1.25*10.12.5

12 1/2=12.5

Answer 2

10 strips

Work:

12 1/2

1/2 = 2/4

12 2/4 divided by 1 1/4 is 10.

Solve:

12 2/4 = 50/4

1 1/4 = 5/4

50/4 divided by 5/4

50/4 * 4/5 = 200/20 = 10
