Question

a. increases
b. decreases
c. stays the same

Answer 1

When multiplying a decimal by a power of 10, the product a. increases.

This is because multiplying by 10 (or any power of 10) shifts the decimal point to the right, increasing the value of the decimal. For example, multiplying 2.5 by 10 gives 25.0, which is a larger number.
