Multiplication with Decimals

Introduction : 

Decimal values are used to symbolize fraction numbers. In the multiplication with decimals are writing exclusive of a fraction having denominator and denominator. Decimal values are might be greater than 1 or less than 1. For the model, the fraction 4/10 might be written as the decimal value as 0.4 and marked as four tenths or zero point four. The decimal of 45/10 is 4.5 which can be marked as four and five tenths. In this article we shall discuss about multiplication with decimals.

Sample Problem for Multiplication with Decimals:

To Multiplying Decimals, we require the following steps.

• Multiplying the two values with null decimal point.

• Once we obtain the final answer, make sure to design the decimal point.

• Number of digits at the back the decimal point in the outcome will be equivalent to the total number of digits after the decimal point in the two numbers being multiplied.

Pro 1:  Solving the decimal multiply for the given values 0.04 by 1.6    

Sol :    Start with: 0.04 x 1.6

Multiply without decimal points: 4x 16 = 72

0.04 has 2 decimal places, and 1.6 has 1 decimal place.

So the answer has 3 decimal places: 0.072

Pro 2:  Solving the decimals multiply for the given values 0.08 by 3.2   

Sol :    Start with: 0.08 x 3.2

Multiply without decimal points: 8 x 32 = 256

0.08 has 2 decimal places, and 3.2 have 1 decimal place.

So the answer has 3 decimal places: 0.256

Pro 3:  Solving the decimals multiply for the given values 0.03 by 2.8   

Sol :    Start with: 0.03 x 2.8

Multiply without decimal points: 3 x 28 = 84

0.03 has 2 decimal places, and 2.8 have the 1 decimal place.

So the answer has 3 decimal places: 0.084

Pro 4 :  Solving the decimals multiply for the given values 0.06 by 4.8   

Sol :   Start with: 0.06 x 4.8

Multiply without decimal points: 4 x 48 = 288

0.06 has 2 decimal places, and 4.8 have the 1 decimal place.

So the answer has 3 decimal places: 0.288


Practice Problem for Multiplication with Decimals:
