Question

Franco read 3/8 of a chapter of his history book in 1/5 of an hour. At this rate, how many chapters of his history book can he read in 1 hour?

Answer 1

He can read
`1(7)/(8)` chapters of his history book in 1 hour.

Step-by-step explanation

Franco read 3/8 of a chapter of his history book in 1/5 of an hour.

Suppose, he can read
`x` chapters of his book in 1 hour at this rate.

So, the equation according to the ratio of 'the chapter to the time' will be....

`(x)/(1)= ((3)/(8))/((1)/(5))\\ \\ (x)/(1)=(3)/(8)*(5)/(1)\\ \\ (x)/(1)=(15)/(8) \\ \\ x= (15)/(8)= 1(7)/(8)`

So, he can read
`1(7)/(8)` chapters of his history book in 1 hour.
