Question

Karen has 3 pieces of ribbon that are each 2 3/4 yd long. She also has a piece of lace that is 3 1/5 yd long. Karen needs to cut the lace into 4 pieces that are all the same length to finish a sewing project. How long should each piece of lace be? A. 1 4/5 yd B. 1 1/4 yd C. 11/12 yd D. 4/5 yd

Answer 1

D) 4/5

Because the lace is 3.2 ydlong, so 3.2÷4=4/5

Answer 2

The first sentence is filler information that can be ignored, as the question involves lace, not ribbon.

Convert the mixed fraction into an improper fraction.


`3 (1)/(5)`

3 * 5 = 15

15 + 1 = 16

The fraction is now
`(16)/(5)`.

Divide the fraction by 4, as you want to get 4 equally long pieces.


`(16)/(5) / (4)/(1) = (16)/(20)`

You get
`(16)/(20)`, which can be simplified to
`(4)/(5)`.

The answer is D.
