Multiplication of whole numbers and multiplication of decimals are two different vehicles with common point called gasoline which is the multiplication concept here. In the case of multiplication of decimals, initially care has to be given to identify how many decimals are there in each of the given number. The two numbers then have to be multiplied by assuming they are like the normal numbers. Once the product is obtained, the decimal point has to be placed and the position of the period is decided by adding the decimal places of the individual numbers that went into the multiplication. This quiz acts as a good exercise for the students to get sufficient practice on decimal multiplication.

How to multiply decimal numbers?

When we multiply decimals, the process is very similar to multiplying whole numbers. However, there are a few extra steps we need to take to make sure we get the correct answer.

To start, let’s look at an example of multiplying decimals:

2.34 x 0.6

The first step is to multiply the numbers just like we would with whole numbers. In this case, that would be 2.34 x 0.6 = 1.404.

However, we need to make sure that our answer has the correct number of decimal places. To do this, we count the total number of decimal places in the original numbers. In this case, there is 1 decimal place in 2.34 and 1 decimal place in 0.6, for a total of 2 decimal places.

So, we need to make sure our answer has 2 decimal places. In this case, it does, so our final answer is 1.404.

Let’s look at another example:

3.456 x 0.7

This time, we have 3 decimal places in the original numbers (1 in 3.456 and 2 in 0.7). So, our answer needs to have 3 decimal places.

When we multiply 3.456 x 0.7, we get 2.4192. This has 4 decimal places, so we need to round it to 3. The correct answer is 2.419.

It’s important to remember that when we multiply decimals, the answer will always have the same number of decimal places as the original numbers. This is because each decimal place represents a certain value (for example, the hundredths place represents hundredths, or hundredths of a whole). So, when we multiply decimals, we are essentially multiplying these values together.

Now, let’s look at how we can use the standard algorithm (the process of multiplying numbers by breaking them down into columns) to multiply decimals.

It’s important to note that when we use the standard algorithm to multiply decimals, we need to make sure to carry over any numbers that are greater than 9. This is because each place in the answer represents a certain value (for example, the ones place represents ones, or whole numbers). So, if we have a number greater than 9 in any place, we need to carry it over to the next place to make sure our answer is accurate
