Adam is making booklets. Each booklet must have 34 sheets of paper. He has two packets of paper. There are 500 sheets of paper in each packet. How many complete booklets can Adam make from two packets of paper?

Adam has two packets of paper each pack has 500 sheets how many sheets of paper does he have altogether. 500 times two or double 500 is 1000. If each booklet must have 34 sheets of paper, how many booklets can Adam make? To calculate the answer, we need to work out how many 34s there are in 1000. 10 lots of 34 is 340. 20 lots of 34 is 680. 20 is double 10. 680 is double 340. To calculate 34 times 30, we just need to add 340 to 680. 600 and 300 is 900. 40 plus 80 is 120 900 plus 120 is 1020.

But Adam doesn’t have 1020 sheets of paper. He only has 1000. We could take away one lot of 34 from 1020. That will tell us how many booklets Adam can make. 1020 take away 30 would be 990. 990 take away four would be 986. So Adam could make 29 booklets.

First, we worked out that Adam had 1000 sheets of paper by multiplying 500 by two. We knew that Adam’s booklets had 34 pages. So we needed to calculate how many 34s go into 1000. We used a known fact 34 times 10 to help us calculate 34 times 29 equals 986. This was the closest we could get to 1000. Now, Adam could make 29 booklets with his 1000 sheets of paper.
