You can use estimation to solve problems with decimals in them. You round the decimal to the nearest ten and add it to the ones place.
 * Estimating Sums and Differences **

Here is an example. 62.7+42.6=105.3

63+43=106

The rounded problem is easier, right? It is easier because you do not have to add the decimals, and you don't have a remainder.
