Answer 2

To calculate :

Numbers rounded to the nearest ten.

Solution :

• A number rounded to the nearest ten is the multiple of 10 nearest to that number.

• For rounding a number to its nearest ten, we have to consider the digit in the units place of that number.

• If the digit in the units place is equal to 5 or greater than 5, then the number in the tens place is increased by one, and the digit in the units place is made 0.

• If the digit in the units place is less than 5, then the digit in the tens place remains as it is, only the units place is made 0.

• We can understand it better by solving the given numbers one by one :

1. 894 = 890 (units place < 5)

2. 643 = 640 (units place < 5)

3. 171 = 170 (units place < 5)

4. 700 = 700 (units place < 5)

5. 735 = 740 (units place = 5)

6. 181 = 180 (units place < 5)

7. 747 = 750 (units place > 5)

8. 245 = 250 (units place = 5)

9. 684 = 680 (units place < 5)

10. 415 = 420 (units place = 5)

11. 149 = 150 (units place > 5)

12. 481 = 480 (units place < 5)

13.246 = 250 (units place > 5)

14. 298 = 300 (units place > 5)

15. 856 = 860 (units place > 5)

16. 497 = 500 (units place > 5)

17. 550 = 550 (units place < 5)

18. 893 =890 (units place < 5)

19. 101 = 100 (units place < 5)

20. 109 = 110 (units place > 5)

21. 936 =​ 940 (units place > 5)
