FRACTIONS AND DECIMALS

On the FIFTH day of math review my teacher taught to me...

HOW TO ADD AND SUBTRACT FRACTIONS

4 - Fractions and Decimals

3 - Traditional Alogorithms

1- And what the operations mean.

**HOMEWORK**

ADDING FRACTIONS WITH LIKE DENOMINATORS

SUBTRACTING FRACTIONS WITH LIKE DENOMINATORS

Think of adding pieces of pizza or cake...

Now think of eating those pieces of pizza or cake... is it lunch time yet?

**UNIT FRACTIONS**

Hmm... what's that mean?

A unit fraction is a fraction with 1 as the numerator.

Are these unit fractions?

3/1

1/7

2/6

10/100

1/999

IMPROPER FRACTIONS

BUT WHAT DO WE DO WHEN THE DENOMINATORS ARE DIFFERENT?!

1. Find a common

denominator

For example:

What is a multiple 3 and 4 have in common?

2. Find equivalent

fractions.

3. Add your new

fractions.

4. Let's try it!

MIXED NUMBERS

When the numerator is BIGGER than the denominator.

**PRACTICE**

Which of these is improper?

2/3

11/5

8/8

12/6

When we have a whole number AND a fraction.
