Question

if the divisor isnt a whole number, what do we do?
move the decimal point to the end of both the numbers.
multiply the divisor by a multiple of 10 (which means hop the decimal point until the divisor is a whole number. then do the same amount of hops to the dividend inside the division box.)

Explanation:

The correct method for dividing when the divisor is not a whole number is to convert the divisor to a whole number by multiplying it by a multiple of 10 (shifting the decimal point right). The dividend must be adjusted by the same multiple of 10 to keep the quotient unchanged. The first option is incorrect because moving the decimal to the end of both numbers is not the standard rule—only shift until the divisor is whole, then apply the same shifts to the dividend.

Answer:

Multiply the divisor by a multiple of 10 (which means hop the decimal point until the divisor is a whole number. Then do the same amount of hops to the dividend inside the division box.)
