Estimate with Decimals

Estimate: is to find something close to the correct answer.

when we estimate the general rule is approximating. if is less than 5 then you round down and if it is greater than 5, you round up.

Example:

4.3          4

10.8       11

I have to round the digit right to decimal number.

I can using the 4 basic operations with decimal: Sums,differences,products,and quotients.
