There are some skills that you will need to master in order to work with fraction operations:

Before this chapter, you should know how to do the following:

- Convert fractions to lowest terms
- Make an equivalent fraction if you know the denominator you want to change the fraction into
- Find the lowest common denominator between two or more fractions
- Convert mixed numbers to improper fractions
- Convert improper fractions to mixed numbers
- Add or subtract fractions with the same denominator
- Add or subtract fractions with different denominators

Today we will review some of these pre-requisite skills and get some practice with our review

There are different ways to think of how to multiply a fraction and a whole number:

- Use a diagram and model how the fractions fit together

- Convert the multiplication to repeated addition

PreClass Assignment:

- Watch the Youtube Videos:
- For each movie, think about what you would say if you were to narrate this video for someone else.

In Class Assignment

- P202 #5a #6, 7, 8, 9, 10, 11, 12 15, *16 *17

Things you should be able to do after today:

- Explain what a whole number x a fraction means as a repeated addition statement
- Multiply a whole number by a fraction and write the answer as an improper fraction or a mixed number
- Convert a word problem to a math statement using multiplication

**Assignment**

- P214 #3, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15, *16

Things you should be able to do after today:

- multiply two or more proper fractions and reduce the answer to lowest terms
- use the cross reducing method to help reduce the multiplication of proper fractions to lowest terms
- represent a word problem using a diagram and use that diagram to determine a multiplication of proper fractions

Proper fractions make up a very small set of numbers; many times, you will need to multiply mixed numbers or whole numbers. It is basically the same as multiplying proper fractions with just a couple different steps that are very important:

- Convert your mixed numbers or whole numbers to improper fractions
- Cross reduce if possible
- Multiply your numerators and multiply your denominators
- Convert your answer back to a mixed number if necessary.

Dividing fractions is an easy process if you think about changing the division to a multiplication question. This is because we can make use of the reciprocal.

For example, we often think of dividing by 2 as taking ½ as taking of something. 2 and ½ are reciprocal numbers. In today's notes, find out how we can use reciprocals to help us divide by a fraction.

- Change a division question into a multiplication question using reciprocals
- Divide using fractions

Fractions are just like regular numbers (decimals and whole numbers), so **order of operations** also applies when mixing operations with fractions. You need to remember the rules for BEDMAS, but also take special care when doing BEDMAS with fractions, because the rules for multiplying, dividing, adding and subtracting with fractions are sometimes different.

Some things you want to remember:

- changing all of your mixed numbers to improper fractions is a good idea (because any multiplying or dividing will require improper fractions anyways)
- adding and subtracting fractions requires common denominators, multiplying and dividing do not
- cross reducing may only be done when multiplying fractions
- dividing by a fraction can be changed into multiplying by a reciprocal
