 Decimals Division with decimals When the dividend is a decimal or mixed decimal. When the dividend is a decimal or mixed decimal, move the decimal point up to the quotient directly above the decimal point in the divident before starting the division. Divide 546.23 by 42 Before starting the division, place a decimal point directly above the decimal point in the dividend: Then divide as with whole numbers. When the divisor is a decimal or mixed decimal. When the divisor is a decimal or mixed decimal, you must first change de divisor to a whole number and then do the division. To change a decimal divisor to a whole number, move the decimal point in the divisor as many places to the right as are necessary to make the divisor a whole number. Move the decimal point in the dividen the same number of places you moved the decimal point in the divisor. Divide 271.88 by 2.8 Move the decimal point in both the divisor and the dividend one place to the right: Then divide as with whole numbers. Divide:
