Best Answer

subtract

$$9\frac{1}{4}-7\frac{1}{2}=1\frac{3}{4}$$

You must convert the fractions to a common denominator before subtracting. Be careful, you must "borrow" 1 from the whole number.

$$8\frac{5}{4}-7\frac{2}{4}=1\frac{3}{4}$$

9 1/4 = 37/4

7 1/2 = 15/2

37/4 - 15/2 =

37/4 / 30/4 =

7/4 lbs left = 1 3/4 lbs.
