BASIC FRACTIONS REVIEW:

*Change a whole # to a fraction

Write a 1 underneath

*ReciprocalsA flipped fraction(based on given

fraction)

DIVIDING FRACTIONS

In all truth and reality, fractions can NEVER be divided!

They can only be MULTIPLIED!!!!

DIVIDING FRACTIONS

Steps:1) KEEP the first fraction

the same.

2) CHANGE the “÷” to “x”

3) FLIP the second fraction to its reciprocal

4) [Cross Reduce &] Solve OR

Solve [& Reduce]

3 ÷ 2 4 5

2 ÷ 3 3 4

3 ÷ 9 4 10

DIVIDING FRACTIONS - PRACTICE

Remember – Everything MUST be in fraction form!

Keep

Change

Flip

Solve (Reduce if possible)

a) 3 ÷ 2 5 3

b) 5 ÷ 5 7

c) 5 ÷ 2 6 3
