Question

Jane says that multiply a decimal by 100 is the same as multiplying the decimal by three factors of 10. Is Jane correct? Explain your answer.

Answer 1

Jane is incorrect, this is because 3 factors of ten equals 1000(10*10*10=1000) and 100 is not equal to 1000 meaning you are not multiplying by the same number.

Answer 2

Jane is incorrect.

Explanation:

We have been given a statement. We are asked to determine whether the given statement is true or not.

Jane says that multiply a decimal by 100 is the same as multiplying the decimal by three factors of 10.

`\text{3 factor of 10}=10^3`

`\text{3 factor of 10}=10* 10* 10`

`\text{3 factor of 10}=1000`

When we multiply a decimal by 100, it will move the decimal to two digits to right and multiplying a number by 1000 will the decimal to three digits to right.

Therefore, Jane is incorrect.
