5. PROPORTIONS In a proportion the product of the means is equal to product of the extremes. 3 : 5 = 6 : 10 Means Extremes

6. SOLVING PROPORTIONS 4 = 24 y 30 4(30) = 24y 120 = 24y 24 24 5 = y 1. Cross Multiply 2. Solve for the variable.

7. SOLVING PROPORTIONS  10 = 5 y 8 8(10) = 5y 80 = 5y 5 5 16 = y  1. Cross Multiply  2. Solve for the variable

8. TRY ONE ON YOUR OWN… 3 = 12 y 28

9. AND ANOTHER… 6 = 12 n 24

10. PROPORTION WORD PROBLEMS If you can buy one can of pineapple chunks for $2 then how many can you buy with $10?  First set up a proportion then solve for your variable.  Remember proportions are two equivalent ratios set equal to each other.  1 can = x $2 $10

11. SOLVING THE PROPORTION 1 can = x cans $2 $10 1(10) = 2x 10 = 2x 2 2 5 = x: You can buy 5 cans with $10.

12. PROPORTION WORD PROBLEMS Ming was planning a trip to Western Samoa. Before going, she did some research and learned that the exchange rate is 6 Tala for $2. How many Tala would she get if she exchanged $6?  First set up a proportion then solve for your variable.  Remember proportions are two equivalent ratios set equal to each other.  6 Tala = x Tala $2 $6

13. SOLVING THE PROPORTION 6 Tale = x Tala $2 $6 6(6) = 2x 36 = 2x 2 2 18 = x: She would get 18 Tala.

14. TRY ONE ON YOUR OWN… Jasmine bought 32 kiwi fruit for $16. How many kiwi can Jasmine buy if she only had $4?  First set up a proportion then solve for your variable.  Remember proportions are two equivalent ratios set equal to each other.
