4. Proportions Key Points: They are forms of equivalent fractions
We will need to cross multiply to find the missing number

5. Proportions
Ex = 4 X

6. Proportions
Ex = 4 X
12(X) = 15(4)

7. Proportions
Ex = 4 X
12(X) = 15(4)
12X = 60

8. Proportions
Ex = 4 X
12(X) = 15(4)
12X = 60

9. Proportions
Ex = 4 X
12(X) = 15(4)
12X = 60
X = 5
