Answer 1

Step-by-step explanation:

You could set up a proportion: “Your score is to 40 as the new score is to 30.” It’s hard to show in the format here, but lets say someone received a 26 out of 40. You could set up the proportion: 26/40 = x/30. You can use cross products to solve (or fraction busters, among other ways) which means 40x = (26)(30) or 40x = 780. Dividing both sides by 40 yields us a 19.5 out of 30.
