What is a Decimal?
A decimal number can be defined as a number whose Whole part and the fractional part is separated by a decimal point. The dot in a decimal number is called a Decimal point.
Multiplying a decimal by Powers of 10
While multiplying any decimal by 10,100,1000, or any other power of 10, we just simply shift the decimal point towards the right as many places as the number of zeroes in the power of 10
If we multiply any decimal by 10, we shift the decimal point one place towards the right, as there is 1 zero in the number 10
If we multiply any decimal by 100, we shift the decimal point two places towards the right.
Similarly, if we multiply a decimal by 1000, we shift the decimal point by three places towards the right, and so on.
For example, 2.32× 10 = 23.2,
2.32×100 = 232,
2.32× 1000= 2320.
Multiplying Decimals with Whole Numbers
Multiplication of decimals with whole numbers is similar to the multiplication of whole numbers, the only difference being in the placement of the decimal point. The following steps can be followed to multiply decimals with whole numbers:
Step 1: Initially, Ignore the decimal point and multiply the two numbers normally.
Step 2: After multiplication, count the number of decimal places in decimal numbers. The product obtained after multiplication will have the same number of decimal places.
Step 3: Place the decimal point in the obtained product following Step 2.
Multiplying Two Decimals Numbers
It is the same as that of the whole number, but the only difference is that in this we have to take the sum of the total number of decimal places in both the given numbers and that needs to be equal to the number of decimal places in the product. To multiply two decimals, follow the step listed below:
Step 1: Initially, Ignore the decimal point and multiply the two numbers normally.
Step 2: After multiplication, count the total number of decimal places in both the numbers combined. The product obtained after multiplication will have this total number of decimal places.
Step 3: Place the decimal point in the obtained product following Step2.
