Question

I read 1/3 of a book in an hour.
How much more of the book will I read in 2 1/5 hours

Answer 1

see below

Explanation:

Here is another way

1/3 book / hr * 2 1/5 hr =

1/3 * 11/5 = 11/15 read in 2 1/5 hr

1/3is the same as 5 /15

11/15 - 5 /15 = 6/15 = 2/5 more read in 2 1/5 hr that 1/3 hr

Answer 2

Explanation:

To find the number of pages of the book in the given hour:

To find the number of pages in 2 1/5 hours, multiply the number of pages read in 1 hour by 2 1/5 hours.

`\sf \text{ Number of pages read in 2 $(1)/(5)$ hours = $(1)/(3)*2(1)/(5)$ }`

`\sf = (1)/(3)*(11)/(5)\\\\=(11)/(15)`

`\sf \text{Number of pages read more in 2 $(1)/(5)$ hours = $(11)/(15)-(1)/(3)$}`

`\sf =(11)/(15)-(1*5)/(3*5)\\\\=(11)/(15)-(5)/(15)\\\\=(6)/(15)`
