Step by step
The question
Question: round 85 to the nearest ten.
Round 85 to the nearest ten
1 Find the two tens
2 Find the closer one
85 is exactly halfway.
Halfway rounds up, to 90.
So 85 rounded to the nearest ten is 90.
The sign ≈ means about.
= 85 ≈ 90
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 8, next digit 5: 5 or more → up
Let's look back.
First: find the two tens.
Then: find the closer one.
Last: check.
Answer
= 85 ≈ 90
