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

Answer: $5.10

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

Answer 2

Answer:

The price Jane had to pay was $5.10.

Step-by-step explanation:

$Total Cost = Length Ribbon * Unit price$

$Total Cost = 12\frac{3}{4} *0.4$

Turning 12 3/4 into an improper fraction:

$12\frac{3}{4} = \frac{12*4+3}{4} = \frac{51}{4}$

Also turning 0.4 into a fraction:

$0.4 = \frac{4}{10}$

Now, we can multiply both fractions:

$Total Cost = \frac{51}{4}*\frac{4}{10}$

Cancelling 4s:

$Total Cost = \frac{51}{10} = 5.10$
