Answer:
40/50
Step-by-step explanation:
The test is worth 50 points in total. Each question is worth 5 points. So,
50 points ÷ 5 points each = 10 questions
If he gets 2 questions wrong,
10 - 2 = 8
He got 8 out of 10 questions right.
Now, multiply by 5 to find his test score out of 50.
8 × 5 ÷ 10 × 5
= 40/50
His test score would be 40/50.
Hope that helps.
