foot long. What was the total length of both pieces of ribbon combined?

Is the student's answer reasonable?

Answer 1

No, the answer is not reasonable. It should be about 1 foot.

Answer 2

No, the answer is not reasonable. It should be about 1 foot

Explanation:

we know that

The correct dimensions are

Gina had two pieces of ribbon. One was 5/8 foot long and the other was 1/4 foot long

so

Sum the length of both pieces

`(5)/(8)+(1)/(4)=(5+2)/(8)=(7)/(8)\ ft`

`(7)/(8)\ ft< 1\ ft`

therefore

No, the answer is not reasonable. It should be about 1 foot
