# Decimals Problem Solving For instance, 4.12 Multiplication and division are inverse operations, so you can expect that if you divide a decimal by a power of ten, the decimal point in the quotient will also correspond to the number of zeros in the power of ten.The difference is that the decimal point moves to the right when you multiply; it moves to the left when you divide.

For instance, 4.12 Multiplication and division are inverse operations, so you can expect that if you divide a decimal by a power of ten, the decimal point in the quotient will also correspond to the number of zeros in the power of ten.

Then move the decimal point in the dividend that number of decimal places to the left; this will be your quotient.

Andy just sold his van that averaged 20 miles per gallon of gasoline.

In the examples above, notice that each quotient still contains the digits 4469—but as another 0 is added to the end of each power of ten in the divisor, the decimal point moves an additional place to the left in the quotient.
