Answer:

The number round to nearest tenths.

Step-by-step explanation:

Given : A number changed to 12.6 after it was rounded.

To find : To what place was the number rounded?

Solution :

The number round when the last digit place value is greater than 5, then before that number rounds by 1 and change the number.

In number 12.6 it was rounded to the nearest tenths.

Which means the hundredths place is greater than 5 either 6,7,8 or 9 and the tenths place is definitely 5.

So, the number can be 12.56, 12.57, 12.58, 12.59

If they all round we get the number 12.6.
