Question

Mia scored 45%, what was her mark out of 40?
A) 18
B) 30
C) 36
D) 25

Answer 1

Mia scored 45% and her mark out of 40 is 18.

Step-by-step explanation:

To find Mia's mark out of 40, you can set up a proportion:

Percentage score / 100 = Mark / Total marks

Plugging in the given values:

45 / 100 = x / 40

Cross multiplying, we get: 45 * 40 = 100 * x

This simplifies to: 1800 = 100 * x

Dividing both sides by 100, we get: x = 18

Therefore, Mia's mark out of 40 is 18.
