Answer:
9/4 yards
Step-by-step explanation:
From the question,some pieces of fabric on sale that each measured 9/10 of a yard. And 2 1/2 of the pieces for the quilt is required to be used.
Then the total length of the fabric she will use can be calculated as
=(2 1/2 of the pieces)×(9/10 of a yard)
=( 5/2 of the pieces)× ( 9/10 of a yard)
= 5/2×9/10
= 45/20
Divide both the denominator and numerator by factor of 5, we have
=9/4
The total length of the fabrics she will use is 9/4 yards
