Question

The chart shows the number of points Corie earned out of the number of points possible on each of the first four units of his math course.

On which two units did Corie earn equivalent scores?

Choose exactly two answers that are correct.

A.Unit 4

B.Unit 1

C.Unit 3

D.Unit 2



Corie's Unit Test Scores
Unit 1 91/100
Unit 2 45/50
Unit 3 18/20
Unit 4 23/25

Answer 1

C & D

Explanation:

Change all the test scores so they have common denominators.

Unit 1 91/100

Unit 2 45/50 * 2/2 = 90/100

Unit 3 18/20 * 5/5 = 90/100

Unit 4 23/25* 4/4 = 92/100

As you can see, Unit 2 and 3 are equivalent.

Answer 2

I believe the answers are C and D. You have to change the test scores so they have common denominators. Correct me if I'm wrong. Hope this helps!
