Question

Moving the decimal point to the right foot places in a number is the same as ______.1. multiplying by 10^42. multiplying by 103. multiplying by 10^-44. multiplying by 4

Answer 1

Whenever we multiply a decimal number by 10, we are shifting the decimal point one digit to the right. For example, if we compute

$12.05\times10$

the answer is

$120.5$

We moved the decimal point one digit to the right; therefore, we can say moving the decimal point to the right foot places in a number is the same as multiplying by 10.

Hence, the correct answer choice is 2
