    So this wants you to add the fractions and subtract 1/1

    we know that 6/8=3/4 because 3/4 times 2/2 (or 1) os 6/8

    so we need the denomenators (bottom number) to be the same

    so 5/6=10/12

    1/4=3/12

    2/3=8/12

    add them together

    10+3+8=21

    21/12=1 and 9/12

    subtract 1 and get

    9/12 left or 3/4 yard left
