DECIMAL FRACTION MULTIPLICATION BY 10, 100, 1000, etc.

__Multiplication By 10, 100, 1000 etc. (Multiples Of 10) -__

**To multiply
decimal fraction by 10, 100, 1000 etc. we move the decimal point in multiplicand by as many places to the right as there are zeroes in the multiplier.**

**1) Multiply
the following decimal fractions by (i) 10; (ii) 100; (iii) 1000 to -**

** a) 9.063**

**i) 9.063 × 10 = 90.63 [The decimal point is moved one place to the right.]**

**ii) 9.063 × 100 = 906.3 [Decimal point is moved two places to
the right.]**

**iii) 9.063 × 1000 = 9063 [Decimal point is moved three places to the right]**

**b) 321.6**

**i) 321.6 × 10 = 3216 [The decimal
point is moved one place to the right.]**

**ii) 321.6 × 100 = 321.6 × 100 = 32160**

**[The decimal point is moved two places to the right.
Since in 321.6 there is only one digit after the decimal
point so we put one zero at the
extreme right of the decimal point as it does not change the value of the number.
Then we multiply 321.60 by 100.]**

**iii) 321.6 × 1000 = 321.6 × 1000 = 321600**

**[The decimal
point is moved three places to the right. Since in 321.6 there is only one digit after the decimal point so we put two
zeroes at the extreme right of the
decimal point as it does not change the value
of the number. Then we multiply 321.600
by 1000.]**
