  3. Dividing DecimalsGetting Started Before you learn to divide decimals, start by taking a look at the steps you should use.

  4. Dividing DecimalsGetting Started : .3633 .06 = Follow these steps when you are dividing decimals.

  5. Dividing DecimalsGetting Started : .3633 .06 = ) Follow these steps when you are dividing decimals. • Write the problem. If the problem is written across, you can copy with the Divisor (number you are dividing by) is outside the division sign. .0 6 .3 633

  6. Dividing DecimalsGetting Started : .3633 .06 = ) Follow these steps when you are dividing decimals. • If the problem is written across, you can copy with the Divisor (number dividing by)is outside the division sign. • Move the decimal point of the Divisor (number you are dividing by) all the way to the right so that it becomes a whole number. .0 6. .3 633

  7. Dividing DecimalsGetting Started : .3633 .06 = ) Follow these steps when you are dividing decimals. • If the problem is written across, you can copy with the Divisor(number dividing by) is outside the division sign. • Move the decimal point of the Divisor (number you are dividing by) all the way to the right so that it becomes a whole number. • Move the decimal point on the Dividendthe SAME number of places to the right as you did on Divisor. Add 0s if you need to move beyond the end of the number. .0 6. .3 6.33

Add 0s if you need to move beyond the end of the number. • Put the decimal point for your answer DIRECTLY ABOVE the one in your dividend. . .0 6. .3 6.33

Add 0s if you need to move beyond the end of the number. • Put the decimal point for your answer DIRECTLY ABOVE the one in your dividend. • Divide the same way you do with whole numbers. After the decimal point, answer with a 0any time a number is too small to be divided. 6.0 5 .0 6. .3 6.33 3 6 3 0 3 3 3 0 3

After the decimal point, answer with a 0any time a number is too small to be divided. • If there is a remainder, add 0s to the number inside the division sign-one at a time, bring them down, and divide until there is no remainder or until there are 4 decimal places in your answer. 6.0 5 5 .0 6. .3 6.33 0 3 6 3 0 3 3 3 0 3 0 3 0 0

  11. Dividing DecimalsPractice Exercises Now, practice the steps for dividing decimals by doing some problems along with me.

  12. Dividing DecimalsPractice Exercises: Problem 1 of 10 : Write this problem down and work through it with me. 1. .25 .5 =

  13. Dividing DecimalsPractice Exercises: Problem 1 of 10 : ) The problem is written across. We can copy it so that the Dividend is inside the division sign and the Divisor is outside the division sign. 1. .5 .25 .5 = .25

  14. Dividing DecimalsPractice Exercises: Problem 1 of 10 : ) Move the decimal point of the Divisor of the division sign 1 place to the right so that it becomes a whole number. 1. .5. .25 .5 = .25

  15. Dividing DecimalsPractice Exercises: Problem 1 of 10 : ) Move the decimal point on dividend 1 place to the right, just as you did on the divisor. 1. .5. .25 .5 = .2.5

  16. Dividing DecimalsPractice Exercises: Problem 1 of 10 : ) Put the decimal point for your answer DIRECTLY ABOVE the one in your dividend. 1. . .5. .25 .5 = .2.5

  17. Dividing DecimalsPractice Exercises: Problem 1 of 10 : ) Divide the same way you do with whole numbers. The answer is .5. 1. .5 .5. .25 .5 = .2.5 2 5 0

  18. Dividing DecimalsPractice Exercises: Problem 2 of 10 : Write this problem down and work through it with me. 2. .0057 .19 =

  19. Dividing DecimalsPractice Exercises: Problem 2 of 10 : ) The problem is written across. Copy it so that the divisoris outside the division sign. 2. .1 9 .0057 .19 = .0 05 7

  20. Dividing DecimalsPractice Exercises: Problem 2 of 10 : ) Move the decimal point of the divisor2 places to the right so that it becomes a whole number. 2. .1 9. .0057 .19 = .0 05 7

  21. Dividing DecimalsPractice Exercises: Problem 2 of 10 : ) Move the decimal point on the dividend 2 places to the right, just as you did on the outside number. 2. .1 9. .0057 .19 = .0 0.5 7

  22. Dividing DecimalsPractice Exercises: Problem 2 of 10 : ) Put the decimal point for your answer DIRECTLY ABOVE the one in your inside number. 2. . .1 9. .0057 .19 = .0 0.5 7

  23. Dividing DecimalsPractice Exercises: Problem 2 of 10 : ) Divide the same way you do with whole numbers. Since the first digit of your answer is after the decimal point, answer with a 0 to show that the 5 can’t be divided by the 19. The answer is .03. 2. .0 3 .1 9. .0057 .19 = .0 0.5 7 0 5 7 5 7 0

  49. Dividing DecimalsPractice Exercises: Problem 7 of 10 : ) The problem is written across. Copy it so that the FIRST number is inside the division sign. 7. 95 .25 = 9 5 .25

  50. Dividing DecimalsPractice Exercises: Problem 7 of 10 : ) Move the decimal point of the number on the outside of the division sign 2 places to the right so that it becomes a whole number. 7. 95 .25 = 9 5 .25.
