MULTIPLYING DECIMALS BY 10 100 AND 1000

When we multiply decimals, accordingly the number of zeros that we have in 10, 100, 1000…etc. we will move the decimals.

Multiplying a decimal by 10 :

1.3 x 10

Here, we have 10, it has one zero. So we have to move the decimal point to the right of one digit.

Multiplying a decimal by 100 :

3.62 x 100

Here, we have 100, it has two zero. So we have to move the decimal point to the right of two digit.

Multiplying a decimal by 1000 :

56.3 x 1000

Here, we have 1000, it has three zero. So we have to move the decimal point to the right of three digit.

Find :

a) 38 x 10	Multiply	380
b) 9 x 100	Multiply	900
c) 3.2 x 10	Since it has one zero, we have to move the decimal point to the right of one digit.	32
d) 0.8 x 10	Since it has one zero, we have to move the decimal point to the right of one digit.	8
e) 0.71 x 100	Since it has two zero, we have to move the decimal point to the right of two digit.	71
f) 2.8 x 100	Since it has two zero, we have to move the decimal point to the right of two digit.	280
g) 0.6 x 100	Since it has two zero, we have to move the decimal point to the right of two digit.	60
h) 0.83 x 100	Since it has two zero, we have to move the decimal point to the right of two digit.	83
i) 1.89 x 10⁴	Here 10⁴ = 10000, it has four zero. So we have to move the decimal point to the right of four digit.	18900
j) 0.053 x 10³	Here 10³ = 1000, it has three zero. So we have to move the decimal point to the right of three digit.	53
k) 0.0583 x 1000	Since it has three zero. we have to move the decimal point to the right of three digit.	58.3
l) 0.187x100000	Since it has five zero, we have to move the decimal point to the right of five digit.	18700
