Question

mr morris put up 3/4 of a fence on monday, 1/6 on tuesday. on wednesday he finished. how much did he put up on wednesday? please show work.​

Answer 1

For this case, we want to know how much fence Mr. Morris put on Wednesday, knowing that day will end.

Monday put:
`\frac {3} {4}`

Tuesday put:
`\frac {1} {6}`

If we add we have:

`\frac {3} {4} + \frac {1} {6} = \frac {4 * 1 + 6 * 3} {24} = \frac {4 + 18} {24} = \frac {22} { 24} = \frac {11} {12}`

To finish the fence, it would fail
`\frac {1} {12}`

If on Wednesday I finish placing the fence, then on Wednesday I put the remaining
`\frac {1} {12}.`

Answer:

On Wednesday Mr Morris placed
`\frac {1} {12}` of the remaining fence

Answer 2

1/12 x

Explanation:

Take x= total lenth of fence

Monday=3/4 x

Tuesday=1/6x

Wednesday=?

3/4 x +1/6 x =11/12 x

remaining =x-11/12 x= 1/12 x
