Question

Molly read 50 out of the 200 pages in her fiction book. Joel is also reading a fiction book, but his book has 280 pages in total. If Joel reads x pages such as the ratio of pages he read is a equivalent to the ratio of pages molly has read, find the value of x.

Answer 1

`x = 70`

Explanation:

Given

Molly: 50 out of 200

Joel: x out of 280

Required

Find x

Start by representing the giving parameters as ration

Molly= 50 : 200

Joel = x : 280

From the question, the ratios are equivalent. So,

`50 : 200 = x : 280`

Convert to fractions

`(50)/(200) = (x)/(280)`

Solve for x

`x = (50)/(200) * 280`

`x = (1)/(4) * 280`

`x = (280)/(4)`

`x = 70`
