rebecca has one piece of fabric that has 2 1/2 piece of fabric and another piece of fabric that is 4 1/4 yards, Rebecca decides to make two quilts for her friends. How many yards of fabric does Rebecca need to make two quilts?

A 6 3/4
B 6 1/3
C 12 2/3
D 13 1/2
My answer is D if they are asking total number of yards to make two quilts
If they are asking how many yards she needs to make two quilts and she already have given amount of fabric then answer is A.
Please help which one is correct.
Thank you!

2 2/4+ 4 1/4 =6 3/4

10 2/4 - 6 3/4 =

Wait hold that was for a different question.

How many yards does she need to make a quilt?

2 1/2+4 1/4 = 6 3/4

To find out how many yards of fabric Rebecca needs to make two quilts, we need to add up the amount of fabric she already has and the amount of fabric needed for two quilts.

First, let's calculate the total amount of fabric Rebecca already has.
Rebecca has one piece of fabric that is 2 1/2 yards long and another piece that is 4 1/4 yards long.

To add these fractions, we need to have a common denominator. In this case, the least common denominator is 4. So we can rewrite 2 1/2 as 2 2/4.

Adding the two fractions:
2 2/4 + 4 1/4 = (2 + 4) + (2/4 + 1/4) = 6 + 3/4 = 6 3/4

So Rebecca already has 6 3/4 yards of fabric.

Now, let's calculate the amount of fabric needed for two quilts.
Since Rebecca wants to make two quilts, she needs twice the amount of fabric for one quilt.

Therefore, the amount of fabric needed for two quilts is:
2 * 6 3/4 = 13 1/2

Therefore, the correct answer is D) 13 1/2.
