How to divide manually decimals
· Transcript. Sal shows how to divide by Dividing decimals. Dividing whole numbers to get a decimal. Practice: Dividing whole numbers like 56÷35 to get a decimal. Dividing a decimal by a whole number. Dividing a whole number by a decimal. Dividing decimals with hundredths. . To divide decimal numbers: Multiply the divisor by as many 10's as we need, until it is a whole number. Remember to multiply the dividend by the same number of 10's. Multiplying by 10 is easy, we just shift one space over like this.
Divide decimals using long division, being sure to multiply by a product of 10 if there is a decimal in the divisor. Place the decimal point in the quotient directly above where it is in the dividend. Ex. ÷ First, multiply both numbers by 10 so there is no longer a decimal in the divisor (). Then, use long division to divide. Step 2: The divisor is not a whole number, so move the decimal point one place to the right to make it a whole number. Move the decimal point in the dividend one place to the right also. 36 Step 3: Divide normally, adding extra zeros to the right of when you run out. 36 3 6 _ 90 72 _ _ 0. 6) Divide 7 and 4 to get 1. Put this on top of the 7 and the division sign. 7) Multiply 4 and 1 to get 4. Place this under the 7. 8) Subtract 7 and 4 to get 3. 9) Add a 0 and a decimal point. Carry down as before. Dividing to a decimal, you can add as many zeroes as the problem requires. 10) Divide 30 and 4 to get 7.
Turn the divisor () into a whole number by moving the decimal point two places to the right. At the same time, move the decimal point in the dividend () two places to the right. Place the decimal point in the quotient directly above where it now appears in the dividend: Now you’re ready to divide. To divide decimals, start by moving the decimal point in the divisor all the way to the right so it's a whole number. Then, move the decimal in the dividend the same number of places to the right. Next, place a decimal point above the division bar directly on top of the decimal point in the dividend. Finally, divide the numbers as you normally would. To divide decimal numbers: Multiply the divisor by as many 10's as we need, until it is a whole number. Remember to multiply the dividend by the same number of 10's. Multiplying by 10 is easy, we just shift one space over like this.
