Question

You read 50 pages in an hour. Your sister reads 40 pages in an hour. Explain how to find out how many more pages you read than your sister reads in 1/2 hour?

Answer 1

25 for 50 pages and 20 for 40 pages

Answer 2

since 1/2 is equal to a half, you divide 50 and 40 by 2 and you'll get 25 and 20 and then you subtract 25 and 20 and you get 5 which is the answer!
