# Common Core: 5th Grade Math : Subtract Decimals

## Example Questions

### Example Question #1 : Subtract Decimals

Subtract:

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

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:

Let's look at this problem:

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

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

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

### Example Question #2 : Subtract Decimals

Subtract the following:

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

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:

Let's look at this problem:

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

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

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

### Example Question #31 : Add, Subtract, Multiply, And Divide Decimals To Hundredths: Ccss.Math.Content.5.Nbt.B.7

Subtract:

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

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:

Let's look at this problem:

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

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

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

### Example Question #32 : Add, Subtract, Multiply, And Divide Decimals To Hundredths: Ccss.Math.Content.5.Nbt.B.7

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. You cannot take  from  so we must borrow a tenth from the tenths place. The  becomes a   and we carry that tenth into the hundredths place making the  a .

Next, subtract the tenths place.

The decimal will be carried down and remain between the tenths place and the ones place.

The final subtraction portion is the ones place.

### Example Question #33 : Add, Subtract, Multiply, And Divide Decimals To Hundredths: Ccss.Math.Content.5.Nbt.B.7

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.

Next, subtract the tenths place

The decimal will be carried down and remain between the tenths place and the one' place.

The final subtraction portion is the ones place.
