Answer 1

`Day\ 3 = 1(3)/(12)`

Explanation:

Given

`Total = 2ft`

`Day\ 1 = (1)/(6)`

`Day\ 2 = (7)/(12)`

Required

Determine the amount of snow on day 3

This can be calculated using:

`Day\ 1 + Day\ 2 + Day\ 3 = Total`

Substitute values for the known parameters

`(1)/(6) + (7)/(12) + Day\ 3 = 2`

Collect Like Terms

`Day\ 3 = 2 - (1)/(6) - (7)/(12)`

Take LCM

`Day\ 3 = (24 - 2 - 7)/(12)`

`Day\ 3 = (15)/(12)`

Express as mixed number

`Day\ 3 = 1(3)/(12)`
