Question

$\text{Find the value of the given division:}0.025÷{10}^3$

• A. 0.0025
• B. 0.0025
• C. 0.000025
• D. None of these

Answer 1

The correct option is C 0.000025

${10}^3=1000$
$0.025÷1000$ is the division of a decimal number by the power of 10.

• To divide a decimal by the power of ten, simply move the decimal point.
• For each zero in the power of 10, move the decimal point one place to the left.

Since there are three zeros in 1000, move the decimal point three places to the left.

Because there is only one digit to the left of a decimal point, we need to add three zeros to the left of the decimal point to move a decimal three places to the left.
$0.025\to \underset{–}{000}0.025$


Hence $0.025÷{10}^3=0.000025$
