Dividing Decimals

 

Examples. Change the following so the second number is a whole number

It's very complicated to divide decimals by hand. 

The easiest way to divide is to change the second number so that it is a whole number.

» you do this by counting how many spaces you move the decimal to the right. 

» Keep in mind what you do to the one number you MUST do it to every number

Dividing Decimals

 

Examples

Once the second number is a whole number you can set up the long division.

» Wherever the decimal is in the first number it stays there on the long division answer.

Dividing FractionsWhen dividing fractions:

Switch ALL mixed fractions to improper fractions first!!!

Then we need to flip the second fraction. 

When this flips, division flips to multiplication. Then we can multiply straight across 

numerator x numerator                              denominator x denominator

Jan 10­1:22 PM

The same rules apply for integers when dividing fractions. 

­ ÷ ­ = +

+ ÷ ­ = ­ 

+ ÷ + = +

­ ÷ + = ­
