__Ratio Proportion Question 1:__


 * 4.)** **Sessions in the swimming pool cost $10 for 5, how much will it be for 20 sessions?

** I solved this problem using the __equivalent fraction__ way by naming the ratios.

You have to come up with a number that's when multiplied to 5, the answer is 20. And that number is **4**. **[ 5 x 4 = 20 ]** Now you must multiply 10 also to 4. **[ 10 x 4 = 40 ]
 * How I got 40:**

Therefore, $40 will be the cost for 20 sessions.**
