What is 31.6 rounded to the nearest hundredth?

Answer 1

31.60

Answer 2

This would be to the nearest whole number.

We can't round to the nearest hundredth because there is no thousandth column to round to the nearest 100th.

Ok, so we have 31 and 6 tenths.

So we find the number that we are using to round to first, in this case the 6 for the full number. If we round 31.6 to 32 we have:

31.7 and 31.8 and 31.9 and 32 (4)

if we round down to 30 we get:

31.5 and 31.4 and 31.3 and 31.2 and 31.1 and 31.0 (6)

So we can see that 31.6 is closer to 32, so we round up to 32.
