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 three tenths. Remember, our one whole block is made up of ten tenths. We can shade in , or three 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 twelve green hundredths blocks, or one tenths block and two hundredths block; therefore, our answer is

Next, we want to shade two 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 six green hundredths blocks and no tenths; therefore, our answer is 

We can first think of this as , which you should know is . But, we need to remember our decimal point. In the problem we have two number after the decimals, so our answer must have two numbers after the decimal point:

The first step when multiplying decimals is lining up the digits on the right-side regardless of place value. It is okay for a tenths place to be in line with a ones place, we want the numbers lined up on the right. 

Then, multiply the digits furthest to the right. In this case, it would be . The  is placed under the problem in the product's area and the  is carried to the top of the problem above the next set of digits. 

Now we will continue multiplying using the  until we have exhausted all digits in the first row. Next is  we must add the  we carried to the top to our product. . Place the  in the product's area and carry the . 

Multiply  and add the  on top . There are no other digits in the top number so we will place the entire  underneath in the product's area. 

You will notice that we have not placed the decimal, that will come at the end of the solution. Now we can cross out the digits we have exhausted and put a placeholder zero in the product's area to hold the place of the furthest right digit that we have finished with. 

It is time to multiply by our final digit,  in , we start back with the furthest right-hand digit, . . Place the  in the products area and carry the  above the next digit we will multiply. 

Continue multiplying,  and add the  on top, . Place the  in the prodict's area and carry your . 

Finally, we are at the last multiplication step before we combine our product.  and we add the  that we carried giving us a total of . The entire  is placed in the product's area because we are out of digits to multiply. 

Now we add our partial products together. 

The last step in a decimal multiplication problem is to place the decimal. Count how many digits are behind the decimal in your problem and we will do the same in the product. This problem has  digits behind the decimal as you can see in pink. 

We will place the decimal in the product so that there are  digits behind it. Giving us a final answer of
