Question

Marita is cutting rolls of ribbon that are 3 feet long into 1/2- foot pieces. She needs fifteen 1/2- foot pieces for a project. She has 3 rolls of ribbon. Does she have enough to cut 15 pieces? Explain.

Answer 1

Answer: Yes

Step-by-step explanation:

3 * 2 = 6. So you can get 6 1/2 foot pieces out of 1 roll. She has 3 rolls. 6 * 3 = 18. 18 is more than 15.

Answer 2

Yes, She have enough ribbon to cut 15 pieces.

What is fraction?

The fraction is numerical representation of the numbers in the form of numerator and denominator.

We have,

Total rolls of ribbon = 3

Length of one roll of ribbon = 3 feet,

So,

Total Length of 3 roll of ribbon = 3 * 3 = 9 feet

And,

Marita cutting rolls into $\frac{1}{2}$ foot pieces.

So,

1 roll cut into pieces $= \frac{3}{\frac{1}{2} } = \frac{3*2}{1}$ = 6 pieces,

So,

3 roll cut into pieces = 6 * 3 = 18 pieces,

i.e.

18 pieces of  $\frac{1}{2}$ foot ,

And she needs $15\frac{1}{2}$ pieces of ribbon,

And total pieces of ribbon are 18.

Hence, we can say that Yes, She have enough ribbon to cut 15 pieces.
