1. 1/10 (3000) = 3000/10 = 300...so 1/10 of 3000 is 300 300/10 = 30...and 300 is 10 times as much as 30
2. 10 times as much as 8 = (10 x 8) = 80 1/10x = 80 x = 80 * 10 = 800 so 1/10 of 800 is 10 times as much as 8
3. 1/10(50,000) = 50,000/10 = 5000 5000/10 = 500 1/10 of 50,000 is 10 times as much as 500
4. 1/10(40,000) = 40,000/10 = 4,000 4000/10 = 400 1/10 of 40,000 is 10 times as much as 400
5. 1/10 (900) = 900/10 = 90 10x = 90 x = 90/10 x = 9 10 times as much as 9 is 1/10 of 900
6. 1/10 (60,000) = 60,000/10 = 6000 10x = 6000 x = 6000/10 x = 600 10 times as much as 600 is 1/10 of 60,000
7. 70 x 10 = 700 1/10x = 700 x = 700 * 10 x = 7000 10 times as much as 700 is 1/10 of 7000
8. 10 x 2000 = 20,000 1/10x = 20,000 x = 20,000 * 10 x = 200,000 10 times as much as 2000 is 1/10 of 200,000
9. 10 times as much as 2000.....2000 x 10 = 20,000 1/10 of what is 20,000.....1/10x = 20,000....multiply both sides by 10, this eliminates the 1/10 on the left side....resulting in 200,000. so basically, 10 times as much as 2000 = 20,000 and 1/10 of 200,000 = 20,000
