One basket contains 24.1 kilograms of apples. Another basket contains 21.5 kilograms of apples. What is the total weight of the apples in the baskets?

The two values in the question are 24.1 kilograms and 21.5 kilograms. As we need to calculate the total weight, we will need to add these two numbers. The easiest way to do this is using column addition. When doing this, it is important that we line up our decimal points. The numbers in each place value column must be lined up underneath each other. The units must be underneath the units, likewise with the tens and the tenths.

We start by adding the numbers in the tenths column. One plus five is equal to six. Therefore, our answer will have six tenths. Four plus one is equal to five. Therefore, our units or ones column will be five. Two plus two is equal to four. Therefore, the answer in our tens column is four. 24.1 plus 21.5 is equal to 45.6.

This means that the total weight of apples in the baskets is 45.6 kilograms.
