Question

Jackie has a roll of ribbon that has 6 feet of ribbon. She is decorating for a birthday party and needs to wrap 10 gifts. Each gift requires 7.5 inches of ribbon. She estimated by multiplying 10 times 7 that she would have enough ribbon for the 10 gifts. Is she correct? Why or why not?

Answer 1

No, she is not correct

Explanation:

She used 7 instead of 7.5 inches, and her answer would be 5.83 feet, and would be under her total 6 feet. But, if she used 7.5 like she was supposed to, she would have gotten 6.25 feet, which would mean she wouldn't have enough.

Answer 2

She does not have enough ribbon.

Explanation:

Each gift is equal to 7.5. Take 10*7.5=75in

In 6 feet how many inches are there? There is 12 in 1 feet. 6*12=72 inches. She would need to round up because of the .5
