What you are doing with proportions most the time is solving for a variable which in this example I will use an x. You have to do something called cross multiplying. now look at number 21. when you cross multiply you multiply the number of the top part of the fraction on the left side to the bottom part of the fraction on the right side. In that example 1 × 36 = 36. now write 36 = 16x since you have to cross multiply the other parts of the fraction. Then you would divide both sides of the equation by 16. I will make a mixed fraction for this example. 2 4/16 which simplified equals 2 1/4
Alright, so there are three answers. Start with 3, and for each question you answer, you can select three more, so it's 3*3 for two questions and so on, resulting in 3^8= 6561
This is assuming you mean <span>how many ways can you answer the test, not the question</span>
