280 and 210

Step-by-step explanation:

For every 4 pages there has to be three more

Therefore we divide the number of pages total by 7

= 70

Geography = 70 * 4 = 280

Civics = 70 * 3 = 210

We add these together to check we have the correct number of pages

We know that the ratio is 4:3 as we multiplied those numbers with 70 respectively
