Question: round 145 to the nearest ten.
Round 145 to the nearest ten
1 Find the two tens
2 Find the closer one
145 is exactly halfway.
Halfway rounds up, to 150.
So 145 rounded to the nearest ten is 150.
The sign ≈ means about.
= 145 ≈ 150
3 Check
We check with the digits.
The next digit after the tens is 5.
5 or more rounds up.
Yes!
It works.
tens digit 4, next digit 5: 5 or more → up
Let's look back.
First: find the two tens.
Then: find the closer one.
Last: check.
