Question

Match the given numbers with the numbers rounded off to the nearest 10.

• A. 15,890
• B. 15,700
• C. 15,800

Answer 1

Always look at the digit at the ones place!
If more than or equal to 5, round up to the next ten.
If less than 5, round down to the previous ten.

15,697 ---> 15,700
Since 7 > 5, we add 1 to the digit in tens place. ⇒ 9 + 1 = 10
Writing 0 in the tens place 0, add 1 to the digit in hundreds place.⇒ 6 + 1 = 7
15,697 rounded off to the nearest 10 is 15,700.

15,795 ---> 15,800
Since 5 = 5, we add 1 to the digit in tens place. ⇒ 9 + 1 = 10
Writing 0 in the tens place 0, add 1 to the digit in hundreds place. ⇒ 7 + 1 = 8
15,795 rounded off to the nearest 10 is 15,800.

15,893 ---> 15,890
Since 3 < 5,
15,893 rounded down to the nearest 10 is 15,890.
