Question

8 1/2- 1 1/4? Show work

Answer 1

`7(1)/(4)`

Explanation:

Change to improper fraction.

`8(1)/(2)` ⇒
`(17)/(2)`

`1(1)/(4)` ⇒
`(5)/(4)`

Find the least common denominator (LCD) of the two fractions. ⇒ 4

`(34)/(4)` -
`(5)/(4)` =
`(29)/(4)`

Convert to a mixed number.

`(29)/(4)` ⇒
`7(1)/(4)`

Hence,
`8(1)/(2) - 1(1)/(4) = 7(1)/(4)`
