Question

Round this number to the nearest one. 51.8

Answer 1

`51.8 \approx52`

to the nearest one.

Explanation:

To round a number to the nearest one is the same as rounding to the nearest unit.

We want to round 51.8 to the nearest one.

Since the number after unit digit is 8 , we round up. That means we need to add 1 to the number in the unit digit and cut off the remaining part to the right of the unit digit.

Therefore

`51.8 = 52`

to the nearest one.
