Estimating quotients worksheet with rounding and division exercises.

I'll solve the problem by estimating the quotients for each division problem on this worksheet. The task is to "Round to comparable numbers" and then estimate the quotient.

Let me go through each problem one by one:

First section (top):
1. 3,536 ÷ 6 → Round 3,536 to 3,600 (close multiple of 6) → 3,600 ÷ 6 = 600
2. 2,148 ÷ 5 → Round 2,148 to 2,000 (close multiple of 5) → 2,000 ÷ 5 = 400

Second section (middle):
3. 1,834 ÷ 8 → Round 1,834 to 1,600 or 2,000; 1,600 ÷ 8 = 200 or 2,000 ÷ 8 = 250. Let's use 2,000 → 250
4. 4,606 ÷ 5 → Round 4,606 to 4,500 or 5,000; 4,500 ÷ 5 = 900
5. 1,620 ÷ 4 → Round 1,620 to 1,600 → 1,600 ÷ 4 = 400
6. 9,657 ÷ 9 → Round 9,657 to 9,000 or 9,900; 9,000 ÷ 9 = 1,000
7. 3,096 ÷ 6 → Round 3,096 to 3,000 → 3,000 ÷ 6 = 500
8. 9,534 ÷ 7 → Round 9,534 to 9,800 (since 9,800 ÷ 7 = 1,400) or 9,100 (9,100 ÷ 7 = 1,300); let's use 9,800 → 1,400
9. 1,321 ÷ 3 → Round 1,321 to 1,200 or 1,500; 1,200 ÷ 3 = 400
10. 1,304 ÷ 2 → Round 1,304 to 1,300 → 1,300 ÷ 2 = 650

Third section (bottom - Estimate the quotient):
11. 4,296 ÷ 7 → Round 4,296 to 4,200 → 4,200 ÷ 7 = 600
12. 8,205 ÷ 9 → Round 8,205 to 8,100 → 8,100 ÷ 9 = 900
13. 5,022 ÷ 5 → Round 5,022 to 5,000 → 5,000 ÷ 5 = 1,000
14. 3,595 ÷ 4 → Round 3,595 to 3,600 → 3,600 ÷ 4 = 900
15. 3,528 ÷ 6 → Round 3,528 to 3,600 → 3,600 ÷ 6 = 600
16. 2,973 ÷ 8 → Round 2,973 to 3,200 → 3,200 ÷ 8 = 400
17. 1,612 ÷ 4 → Round 1,612 to 1,600 → 1,600 ÷ 4 = 400
18. 4,234 ÷ 5 → Round 4,234 to 4,000 → 4,000 ÷ 5 = 800
19. 4,254 ÷ 9 → Round 4,254 to 4,500 → 4,500 ÷ 9 = 500
20. 1,612 ÷ 6 → Round 1,612 to 1,800 → 1,800 ÷ 6 = 300
21. 1,234 ÷ 2 → Round 1,234 to 1,200 → 1,200 ÷ 2 = 600
22. 3,321 ÷ 7 → Round 3,321 to 3,500 → 3,500 ÷ 7 = 500
23. 3,931 ÷ 6 → Round 3,931 to 4,200 → 4,200 ÷ 6 = 700
24. 2,607 ÷ 5 → Round 2,607 to 2,500 → 2,500 ÷ 5 = 500
25. 5,264 ÷ 2 → Round 5,264 to 5,200 → 5,200 ÷ 2 = 2,600
26. 3,525 ÷ 3 → Round 3,525 to 3,600 → 3,600 ÷ 3 = 1,200
27. 2,302 ÷ 5 → Round 2,302 to 2,500 → 2,500 ÷ 5 = 500
28. 6,621 ÷ 2 → Round 6,621 to 6,600 → 6,600 ÷ 2 = 3,300

The key strategy here is to round the dividend (the number being divided) to a number that is easily divisible by the divisor (the number you're dividing by), making mental calculation simpler while still providing a reasonable estimate of the actual quotient.
