Round 656.692169912 to 1 decimal place. I am so confused.

You would round it to 656.70 because the 9 behind the 6 is greater than 5 so it rounds up and makes 6 and 7 and all the numbers behind 6 zero.

Hence, the required number is 656.7

Step-by-step explanation:

Consider the provided number.

656.692169912

We need to round the number to the 1 decimal place.

There are 9 digits after the decimal place.

First understand the means of rounding to the 1 decimal place.

The meaning of rounding to the 1 decimal place is Round the number value after the integer number, restricted to one decimal place.

For example: Consider the number 8.14 is rounded to 8.1

The rule of rounding a number is:

If 0, 1, 2, 3, or 4 follow the number, round it down.

If 5, 6, 7, 8, or 9 follow the number, round it up.

Now consider the number 656.692169912

The number at 2 decimal place was 9, so to round the 1 decimal place round the number up.

Thus round the number 656.692169912 to the 1 decimal place is:

656.7

Hence, the required number is 656.7
