Question

Sheryl has 7 3/4 hours this weekend to work on her new video. She estimates it will take 2 1/2 hours to lip sync the new song and 2 2/3 hours to learn the new dance steps. How much time will she have left for her VTV interview?

Answer 1

The total time that Sheryl has is 7 3/4 hours

she spends 2 1/2 hours lip-sync the new song

she spends 2 2/3hours learning the new dance steps.

The time she has for her VTV interview

`7\text{ }(3)/(4)-2(1)/(2)-2(2)/(3)`
`(7-2-2)+((3)/(4)-(1)/(2)-(2)/(3))=3+(-(5)/(12))=(36)/(12)-(5)/(12)=(31)/(12)=2(7)/(12)`

She will have 2 7/12 for her interview
