Question

Jane bought a 12 3/4 ft. string of ribbon from the party store. It costs $0.40 per foot. How much did she pay?

Answer 1

The price Jane had to pay was $5.10.

Explanation:

`Total Cost = Length Ribbon * Unit price`

`Total Cost = 12(3)/(4) *0.4`

Turning 12 3/4 into an improper fraction:

`12(3)/(4) = (12*4+3)/(4) = (51)/(4)`

Also turning 0.4 into a fraction:

`0.4 = (4)/(10)`

Now, we can multiply both fractions:

`Total Cost = (51)/(4)*(4)/(10)`

Cancelling 4s:

`Total Cost = (51)/(10) = $5.10`

Answer 2

Answer: $5.10

Step-by-step explanation: 12 3/4 divided by 0.40
