Answer 1

B. Multiply by a power of 10 until both numbers have the same place values.

Answer 2

when dividing by a decimal,

Multiply by a power of 10 until you are dividing by a whole number.

Explanation

Lets see what power of 10 to multiply a divisor and dividend by when dividing by a decimal

For example

$\frac{34}{2.5}$

Here we have divisor 2.5 that has 0ne decimal place

So we multiply the divisor by 10 to remove the decimal point

we multiply both top and bottom by 10. so that decimal gets removed from the divisor

$\frac{32}{0.32}$, here we multiply the divisor by $100 \; or \; 10^2$ so that the decimal in the divisor will be removed.

S0,  Multiply by a power of 10 until you are dividing by a whole number.
