Explanation

Subtracting decimals is just like subtracting whole numbers. But, you must remember your decimal in your answer.

You start subtracting on the far right which in this case is the hundredths place. Screen shot 2020 09 11 at 8.31.19 am

Next, subtract the tenths place Screen shot 2020 09 11 at 8.31.37 am

The decimal will be carried down and remain between the tenths place and the one' place. Screen shot 2020 09 11 at 8.31.48 am

The final subtraction portion is the ones place. Screen shot 2020 09 11 at 8.31.54 am

Explanation

We can use base ten blocks to help us solve this problem. Let's review what our base ten blocks are by using a whole number

Base ten blocks

When we put this together, we add:

To use base ten blocks to add decimal numbers, we need to think of the base ten blocks a little differently. We think of the hundreds block as one whole. The tens block as tenths because you would need ten of these to make one whole. Finally, the ones block as hundredths because you would need a hundred of these to make one whole:

Base ten blocks decimal

Let's look at this problem:

First, we want to represent the with four tenths blocks and five hundredths blocks:

45

Next, we want to take away , which means taking away one of the tenths and one of the hundredths:

34

We can see that we now have three tenths blocks and four hundredths blocks, which means our answer is

Let's look at this problem:

First, we want to represent the with one tenths block and five hundredths blocks:

15

Next, we want to take away , which means taking away none of the tenths and two of the hundredths:

13

We can see that we now have one tenths block and three hundredths blocks, which means our answer is
