Question

Multiply $0.67$ by $10,100$ and $1000$ respectively.

Answer 1

Step 1. When a decimal is multiplied by 10, the decimal point shifts one place to the right.

$0.67\times 10=6.7$

Step 2. When a decimal is multiplied by 100, the decimal point shifts two place to the right.

$0.67\times 100=67$

Step 3. When a decimal is multiplied by 1000, the decimal point shifts three place to the right and so on.

$0.67\times 1000=670$

Hence, the required results are $6.7,67$ and $670$
