Example Question #2 : Add, Subtract, Multiply, And Divide Decimals To Hundredths: Ccss.Math.Content.5.Nbt.B.7
Divide:
We can use base ten blocks to help us solve this problem. First, we want to use base ten blocks to represent
Because we are dividing by , we need to split up our into groups of
We can see that we have 2 groups of 2, thus the answer is 2.
Example Question #671 : Number & Operations In Base Ten
Divide:
We can use base ten blocks to help us solve this problem. First, we want to use base ten blocks to represent .2
Because we are dividing .2 by .2, we need to split up our .2 into groups of .2:
We can see that we have 1 group, thus our answer is 1.

Example Question #672 : Number & Operations In Base Ten
The problem that you are challenged to solve is .
is the dividend, this is what is being broken up into groups. is our divisor which is the number of groups you are making. We need to split in half to see how many are in each group.
The first step is to place your decimal above your equation in the same place. It will line up with the decimal inside of your "long-division house".
Next, we need to use or multiplication facts to determine what can be multiplied by to make or get close to it without going over. is the fact that works best ( is too large). We will place the numeral directly above the in the ones place to indicate that groups of fit into the . We will put the product of which was underneath the in the ones place and subtract the difference. The numbers above the "house" are our quotient or answer to the division problem.
Next, we will carry the in the tenths place down and put it next to the . We will work with the numbers as if they were when thinking of multiplication facts, but it should be noted this is actually when you consider the decimal placement. so we place the above the "house" in the tenths place of our quotient and subtract the . We are left with remaining so there is no remainder.
Our final answer is , which means that half of is
Example Question #673 : Number & Operations In Base Ten
The problem that you are challenged to solve is .
is the dividend, this is what is being broken up into groups. is our divisor which is the number of groups you are making. We need to split in thirds to see how many are in each group.
The first step is to place your decimal above your equation in the same place. It will line up with the decimal inside of your "long-division house".
Next, we need to use or multiplication facts to determine what can be multiplied by to make or get close to it without going over. is the fact that works best ( is too large).

We will work with the numbers as if they were when thinking of multiplication facts, but it should be noted this is actually when you consider the decimal placement. so we place the above the "house" in the tenths place of our quotient and subtract the . We are left with remaining.
Finally, we carry down the from the hundredths place and place it next to the giving us (or for the purpose of our multiplication facts.) so we place the above the in the hundredths place on top of our "house" and subtract the leaving us with a remainder of .
Our final answer is
Example Question #674 : Number & Operations In Base Ten
The problem that you are challenged to solve is .
is the dividend, this is what is being broken up into groups. is our divisor which is the number of groups you are making. We need to split in quarters to see how many are in each group.
The first step is to place your decimal above your equation in the same place. It will line up with the decimal inside of your "long-division house".

Example Question #671 : Number & Operations In Base Ten
Multiply:
When multiplying decimals, we can use our base ten blocks to create an area model. To do this, we want to use our hundreds, or one whole, block:
is equal to five tenths. Remember, our one whole block is made up of ten tenths. We can shade in , or five tenths blocks, of the whole. Let's shade of the vertical tenths blocks. Let's use blue to shade:
Next, we want to shade four of the tenths blocks to represent the . Since we shaded vertical for the first step, we need to shade horizontal for this step. Let's use yellow to shade:
Notice the green shading. This is where the yellow and the blue shading overlapped. (Remember, yellow and blue make green). The overlapping section is our answer. There are twenty green hundredths blocks; therefore, our answer is which is equal to two tenths, :
