Question

Brendan worked 7 11/12 hours on Saturday, on Sunday he worked 84% of the hours he worked on Saturday. How many total hours do he work last weekend?

Answer 1

`14(17)/(30)`hrs

Explanation:

Given parameters:

Time worked on Saturday =
`7(11)/(12)`

Unknown:

Total hours he worked last weekend = ?

Solution:

Since Brendan worked 84% of the time he worked on Saturday on Sunday;

Time worked on Sunday =
`(84)/(100)` x
`(95)/(12)` =
`(133)/(20)`

Total time worked last weekend = Time worked on Saturday + Time worked on Sunday;

Total time worked =
`(95)/(12)` +
`(133)/(20)`

Total time worked =
`(475 + 399)/(60)`

Total time worked =
`(874)/(60)`

Total time worked =
`(437)/(30)` =
`14(17)/(30)`hrs
