Question

How to round a whole number to the nearest tenth?

Answer 1

 For example, if we want to round to the nearest ten, we will look at the ones place.If this next smallest place value is less than five (0, 1, 2, 3, or 4), we leave the digit we want to round to alone. Any digits after that number (including the next smallest place value we just looked at) become zeros, or simply drop if after the decimal point. This is called rounding down

If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), we increase the value of the digit we're rounding to by one. Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.

324.5 
Identify the tens digit: 324.5Identify the next smallest place value (the digit to the right of the tens place): 324.5Is that digit greater than or equal to five? NO - we round DOWNThe tens digit stays the same. Every digit after it becomes a zero. Digits after the decimal point are dropped.

Answer 2

How to round a whole number to the nearest tenth.

When rounding whole numbers to the nearest tenth, you need to look at the ones place, if the number is smaller than 5, then round down. If the number in the ones place is greater than 5, then round up.

Example:- If they told me to round 67 to the nearest tenth, I need to find the ones place. 

The ones place in 67 is the 7.

7 is greater than 5, therefore, we need to round up.

We round 67 to 70.

So our answer is 70.
