Question

If math students typically earn 24 points out of 35 possible on a test, how many points would be typical if there were 100 possible points? Round to the nearest tenth

Answer 1

68.6

Explanation:

Given the initial ratio of 24 points out of 35 possible points, you can set up a proportion (equivalent ratios) to find the expected number of points math students would ear on a test of 100 possible points:

`(earned)/(possible)=(24)/(35)=(x)/(100)`

Where 'x' is the number of points earned on the 100 point test.

Cross-multiply: 35x = 24(100) or 35x = 2400

Divide both sides by 35: 35x/35 = 2400/35

Solve for x: x = 68.6
