Question

$0.00112	imes1000$ is equal to:

Accepted Answer

The correct option is 2:
To multiply a decimal number by 10, 100, 1000, and so on, we simply move the decimal point to the right by the number of zeros in the multiplier. In this case, we are multiplying by 1000, which has three zeros.

Step 1: Identify the given decimal number and the multiplier.
The decimal number is $0.00112$.
The multiplier is $1000$.

Step 2: Count the number of zeros in the multiplier.
The multiplier $1000$ has three zeros.

Step 3: Move the decimal point in the decimal number to the right by the number of zeros counted in Step 2.
Starting with $0.00112$, move the decimal point three places to the right:
$0.00112 ightarrow 00.0112 ightarrow 001.12 ightarrow 001.12$

Step 4: Simplify the result by removing any leading zeros that are no longer significant.
$001.12$ simplifies to $1.12$.

Therefore, $0.00112 	imes 1000 = 1.12$.

The incorrect option is 1: This option, $0.112$, would be the result if the decimal point were moved only two places to the right, as if multiplying by $100$ instead of $1000$.

The incorrect option is 3: This option, $112$, would be the result if the decimal point were moved five places to the right, or if the number was incorrectly read as $112$ without considering the decimal places in the original number.

The incorrect option is 4: This option, $11.2$, would be the result if the decimal point were moved four places to the right.
