Decimal Division

2
**To divide a decimal by a whole number move the decimal point straight up and then divide as usual**

3
Example: 3 Move your decimal point straight up, then divide

Let’s do a few together 4

6
To divide a decimal by a decimal move the decimal point in the divisor over to make a whole number:

7
**Now, move the decimal point**

in the dividend over the same number of spaces and then move your decimal point straight up and divide

**Dividing Decimals “Swingin’ Monkeys”**

10
Swinging Monkeys! Follow these steps and you will be great at dividing decimals! Remember: Whatever the OUTSIDE monkeys do – the INSIDE monkeys do also! Monkey See; Monkey Do!

**Division Vocabulary “Roof” Quotient “Outside” Divisor “Inside”**

Dividend

12
Division Vocabulary 12.64 ÷ .2 12.64 divided by .2

13
**Steps in Dividing Decimals**

Make the divisor (outside number) a whole number by moving (swingin’) the decimal to the right as many places as it takes to make it a WHOLE NUMBER. In MONKEY TERMS: Whatever the outside monkey does (how far it swings) the inside monkey does also. Then the monkey climbs up and sits on the roof!

**Swingin’ Monkeys Divisor**

Moved (swung) the decimal point 1 place to the right Swingin’ Monkey

**Steps in Dividing Decimals**

2. Move (swing) the decimal point in the dividend the same number of places as the divisor. Dividend Moved (swung) the decimal point 1 place to the right

3. Place (swing) the decimal point in the answer (quotient) lined up with the decimal point in the dividend (on the roof).

4. Now, divide as usual!

**Steps in Dividing Decimals**

4. Divide the numbers. Make sure the decimal point stays lined up. 6 3 2 12 6 6 4

20
**What is actually happening . . .**

When you move the decimal one place to the right to create a WHOLE number – you are actually multiplying it by 10! When you move the decimal two places to the right to create a WHOLE number – you are actually multiplying it by 100! Three?

21
Let’s Practice Remember: The more neatly you write and keep the numbers lined up, the BETTER!

22
Your Turn - Practice 14.2 ÷ 0.2 = 25.5 ÷ 1.5 =
