Antoine Mueller · Answer 1

So you start by adding the two numbers on either side of your ratio together ...

4 + 3 = 7

Then you divide your total number (the book pages) by your total ratio number ...

490/7 = 70

Finally, you multiply each side by 70.

4 x 70 = 280 geography

3 x 70 = 210 civics

Plus, you can check your answer by adding the two totals ...

280 geography + 210 civics = 490 pages total
