Question

Jamie is cutting for a craft project.she has a ribbon that is 2 1/4 inches long. How many pieces of ribbon can she cut that are 3/8inches long

Answer 1

Total Lenght = 2 1/4

Lenght of each piece = 3/8

Divide the total lenght by the lenght of each piece:

Total lenght = 2 1/4 = (2*4+1)/4 = 9/4

Total lenght / lenght of each piece = (9/4 ) / (3/8)

To divide 2 fractions we can multiply by the inverse of the second fraction:

$\frac{9}{4}\times\frac{8}{3}=\frac{72}{12}$

Simplify by 12:

6

Answer: 6 pieces
