particular dress requires 3 1/4 yards of fabric for manufacturing. If the matching jacket requires 5/6 yard less fabric, how much fabric is needed for both pieces?
Do not enter units in your answer
The jacket requires [3 + 1/4] - [5/6] = [13/4] - [5/6]....the common denominator is 12, so the fractions become:
[39/12 - 10/12] = [29/12] = [2 + 5/12]
So the total requirement is:
[3 + 1/4] + [2 + 5/12] = [3 + 3/12] + [ 2 + 5/12] = [5 +8/12] = [ 5 + 2/3]
+87
