Rounding to the Nearest Ten with a 2-Digit Number (Lesson)
When rounding a two‑digit number to the nearest ten, look at the ones digit.
- If the ones digit is 5 or higher, increase the tens digit by one and round up to the next ten.
- If the ones digit is 4 or lower, keep the tens digit the same and round down to the lower ten.
Example: Round 47 to the nearest ten.
The tens digit is 4, which represents 40.
The ones digit is 7, which tells us whether to round up or down.
Since the ones digit is 5 or greater, we increase the tens digit by 1, and round up to 50.
So, 47 rounds to 50.
Example: Round 32 to the nearest ten.
The tens digit is 3, which represents 30.
The ones digit is 2, which is less than 5.
Since the ones digit is 4 or less, we keep the tens digit as it is, and round down to 30.
So, 32 rounds to 30.
