The fabric needed for both pieces is 94/12 yards
Fractions are ratio of two integers. Fractions are written in the form of a/b.
Given the following parameters
Measure of dress fabric = 4 1/4 yards
If the matching jacket requires 2/3 yards less fabric, the amount of the other fabric is (17/4 - 2/3) = 17(3)-2(4)/12= 43/12 yards
Determine the total fabric.
Total fabric = 17/4 + 43/12
Total fabric = 51+43/12
Total fabric = 94/12
Hence the fabric needed for both pieces is 94/12 yards
