Question

john weighs 150 7/8 ponds.his son weighs 48 1/4 pounds less. how much does his son weigh?

Answer 1

John's son weighs 48 1/4 lbs less than John's 150 7/8 lbs.

Note that 1/4 can be rewritten as 2/8 simply by multiplying both the numerator and denominator by 2.

Now it is easy to find the son's weight.

150 7/8 - 48 2/8 = (150-48) + (7/8 - 2/8) = 102 + 5/8 = 102 5/8 lbs.
