Dividing a Decimal by a Whole Number
Dividing a Decimal by a Whole Number is a Grade 5 math skill from Eureka Math that teaches students to perform long division when the dividend is a decimal. Students line up the decimal point in the quotient directly above its position in the dividend and then proceed with the standard long division algorithm. This skill extends whole number division fluency to the decimal domain.
Key Concepts
To divide a decimal by a whole number, place the decimal point in the quotient directly above the decimal point in the dividend. Then, divide using the standard algorithm as you would with whole numbers.
Common Questions
How do you divide a decimal by a whole number?
Set up long division with the decimal as dividend. Bring the decimal point straight up into the quotient directly above its position in the dividend, then divide as usual digit by digit.
What happens to the decimal point when dividing a decimal by a whole number?
The decimal point in the quotient is placed directly above the decimal point in the dividend. The digits of the quotient fall into the correct place value positions automatically.
What Eureka Math Grade 5 chapter covers dividing decimals by whole numbers?
Eureka Math Grade 5 covers dividing a decimal by a whole number in its decimal division chapters, building on whole number long division fluency.
How is dividing a decimal by a whole number similar to whole number division?
The procedure is identical. The only addition is placing the decimal point in the quotient directly above the decimal in the dividend before starting the calculation.
What is 3.6 divided by 4?
Set up 3.6 ÷ 4. Place the decimal in the quotient above the decimal in 3.6. Then: 4 goes into 36 nine times with no remainder. So 3.6 ÷ 4 = 0.9.
