### Decimals, Fractions, Integers

## Decimals in Dividend Place the decimal point in the quotient directly above where it is in the dividend. Ignore the decimal point and divide normally. | ## Decimals in Divisor & Dividend Change the divisor to a whole number by moving the decimal all the way to the right. Then move the decimal in the dividend the same number of places to the right. Place the decimal point in the quotient directly above where it is in the dividend. Ignore the decimal point and divide normally. REMEMBER: Monkey see, Monkey do! | ## Add Zeros We do not want a remainder when we are dividing with decimals. You can add zeros to the right of the decimal and not change the value of the decimal. |
