Question

30 rounding to the nearest ten

Answer 1

Rounding is based on if the number is greater than 5, if it is indeed greater than 5 it precedes to a higher number.

For instances, 37 rounds up to 40 or with smaller numbers 5 rounds to 10.

To address this question, 30 does not round  up nor down, it remains as 30 because the ones place is less than 5.

To summarize

• Round up when the ones place is 5 or higher
• Do not round if it is lower than 5
• Ex: 37 --> 40
• Ex:  22 --> 22
