Question

Rocky spends 1 3/4 hours working out

on Monday, 2½ hours on Wednesday and 5/6 of
an hour on Friday. How much time did he spend
working out this week.

Answer 1

5 1/12 hours

Explanation:

You need a common denominator and that would be 12

1
`(9)/(12)` (
`(3)/(4)` x
`(3)/(3)`) another name for
`(3)/(3)` is 1. You are making an equivalent fraction

2
`(6)/(12)` (
`(1)/(2)` x
`(6)/(6)`)

`(10)/(12)` (
`(5)/(6)` x
`(2)/(2)`)

1
`(9)/(12)` + 2
`(6)/(12)` +
`(10)/(12)` = 3
`(25)/(12)`

I can break
`(25)/(12)` into
`(12)/(12)` +
`(12)/(12)` +
`(1)/(12)` Another name for
`(12)/(12)` is 1

3 + 1 + 1 +
`(1)/(12)`

5
`(1)/(12)`
