Ruth needs 3 1/4 yards of fabric to make a small quilt. She has 1 7/8 yards in her fabric box. how much more fabric does she need to buy?
3 1/4 - 1 7/8
= 3 2/8 - 1 7/8
= 2 10/8 - 1 7/8
= 1 3/8
Thank you!
To find out how much more fabric Ruth needs to buy, we need to subtract the amount of fabric she already has from the total amount she needs.
First, let's convert both the amounts to mixed numbers to make the subtraction easier:
1 7/8 yards is equal to 15/8 yards.
3 1/4 yards is equal to 13/4 yards.
Now, subtract the amount of fabric Ruth already has from the total amount she needs:
13/4 - 15/8
Since the denominators are different, we need to find a common denominator. In this case, the common denominator is 8, so we need to convert 13/4 into an equivalent fraction with a denominator of 8:
13/4 x 2/2 = 26/8
Now we can subtract:
26/8 - 15/8 = 11/8
So, Ruth needs to buy an additional 11/8 yards of fabric to have enough for her small quilt.
To convert the fraction to a mixed number, we divide the numerator (11) by the denominator (8):
11 ÷ 8 = 1 remainder 3
Therefore, she needs 1 3/8 yards of fabric more to complete her quilt.
