Question

Brooke played her flute for 3/4 hour each day for 5 days and for 1/2 hour each day for 2 days how many hours did she play it in all

Answer 1

⇒To be able to answer this question to find how many hours Brooke played his flute for 5 days we ought to first convert the 5 days to hours.

⇒There are 24 hours in a day this means that in 5 days we have =24×5

=120 hours.

⇒We have 120 hours in 5 days , it is said that Brooke played her flute
`(3)/(4)`,

Meaning she played the flute
`(3)/(4)` hours of 120 hours which is equal

`(3)/(4) *(120)/(1)\\=90`

For 5 days Brooke played her flute 90 hours

⇒The next step is to convert the 2 days to hours which is equivalent to 24×2

=48 hours are in 2 days, it is said Brooke played the flute
`(1)/(2)` hours of 2 days. This simply is equivalent to

`(1)/(2) *(48)/(1) \\=24`

⇒For 2 days Brooke played the flute 24 hours,

The total number of hours she played it all is =Number of hours she played it in 5 days+ Number of hours she played it in 2 days.

=90+24

=114

⇒In total of these 7 days she played the flute for 114 hours
