Improper Fractions
the numerator part greater or equal to the denominator
ex-17/2 or 5/5
How to make an improper to a mixed:
DIVIDE the numerator by the denominator. Whole number is quotient, remainder is new numerator and denominator stays the same.
Practice / / /4
Mixed Fractions
a whole number plus a fraction
ex-2 ½ or 1 ¼  .      
How to make a mixed an improper:
Multiply the whole number by the denominator, then add on the numerator. This is your new numerator. The denominator stays the same!
Practice ¼ ¾ /5
Remember to simplify whenever possible!

Multiplying and Dividing Fractions 6.6
Multiplying
* Any mixed or whole number must be made improper before multiplying
1. Multiply the numerator
2. Multiply the denominators
Ex- ¾ x ½= 3/8
Ex- 2 ½ x 1 ¾ = 5/2 x 7/4= 35/8= 4 3/8
Ex- 3 x 5/6 = 3/1 x 5/6= 15/6 = 2 3/6= 2 ½
Ex- ½ OF 8= ½ x 8= ½ x 8/1= 8/2= 4
Dividing
Flip (reciprocal) the second fraction and change the sign to multiplication.
Follow the steps for multiplication
KEEP CHANGE FLIIP!!!
Ex ¾ ÷ ½= ¾ x 2/1= 5/4= 1 ¼
Ex 2 ¼ ÷ 5= 9/2 ÷ 5/1 = 9/2 x 1/5= 9/10
Pg Practice
3/8 x 2/3=
1/3 x 5/6=
4/5 x 2/9=
9 1/3 x 2 2/3=
20 x 1 ½=
2/5 of 60=
18 ÷ 2 ½=
4 1/9 ÷ 6 2/3
¾ ÷ 2=
