Question

How do I compare these decimals? 5.213 ; 5.312

Answer 1

See below on one idea:

Explanation:

We can look to see which is bigger - I'm assuming that is meant by asking how to compare the two decimals.

`5.213`
`5.312`

First we look to the ones place and see that the numbers are same:

`underbrace(5)_("Ones").213`
`overbrace(5).312`

Then we move to the next position, the tenths, and see which number is bigger. `3>2` and so `5.312>5.213`:

`5.underbrace(2)_("Tenths")13`
`5.overbrace(3)12`
