I turn the mixed numbers into decimals before doing anything else.
11 2/5----> 57/5----> 11.4
4 2/7----> 30/7----> 4.29
2 1/7----> 15/7----> 2.14
11.4=q-4.29+2.14
11.4=q-2.15
13.55= q
13.55 converted to a fraction is 13 11⁄20
q=13 11⁄20
To convert the value from inches to yards, we need a conversion factor to multiply it to the value that will equate it to yards. From a conversion table, we see that 1 inch is equal to 0.02778 yards. We multiply this value.
16.7 inches ( 0.02778 yards / 1 inch ) = 0.464 yards = 4.6 x 10^-1 yards
