Question

Sarah read her book for 2 1/8hours on Monday, 1 1/2hours on Wednesday, and 1 3/4hours on Friday.How many hours did she read her book in all?I did the problem and got 4 11/8 I know that 8/8 is equals 1 so so 11/8 is closer to 1 1/2 what am I missing one step.

Answer 1

It is given that

On Monday she reads

`(17)/(8)h`

On Tuesday she reads

`(3)/(2)h`

On Wednesday she reads

`(7)/(4)h`

The total hours she reads the book in all

`(17)/(8)+(3)/(2)+(7)/(4)=(17+12+14)/(8)=(43)/(8)`
`(43)/(8)h=5(3)/(8)h`

Hence the correct option is D.
