How to Multiply Decimal Numbers by 10, 100, 1000

Multiplying by 10:
To multiply a decimal number by 10, simply move the decimal point one place to the right. For example, if you have the decimal number 3.45 and you want to multiply it by 10, the result would be 34.5 (3.45 x 10 = 34.5).

Multiplying by 100:
To multiply a decimal number by 100, move the decimal point two places to the right. For example, if you have the decimal number 5.67 and you want to multiply it by 100, the result would be 567 (5.67 x 100 = 567).

Multiplying by 1000:
To multiply a decimal number by 1000, move the decimal point three places to the right. For example, if you have the decimal number 8.912 and you want to multiply it by 1000, the result would be 8912 (8.912 x 1000 = 8912).
Remember, when you multiply a decimal number by 10, 100, or 1000, you are essentially increasing the value of the number by a factor of 10, 100, or 1000 respectively. This is a quick and easy way to perform multiplication by these numbers without having to do complex calculations.
