Question

A month ago, kerry weighed 123 1/4 pounds. now he weighs 120 1/2 pounds. how many pounds did he lose?

Answer 1

Old weight =
`123 (1)/(4) = (493)/(4)`

New weight =
`120 (1)/(2) = (241)/(2)`

Hence, weight lost =
`(493)/(4) - (241)/(2) = (493-2*241)/(4) = (493-482)/(4) = (11)/(4) = 2 (3)/(4)`

Hence, the answer is
`2 (3)/(4)` pounds.

Answer 2

123 1/4 - 120 1/2 = 2 3/4
