Matilda answered 12 of the 15 problems or a ratio of 12:15 ...

This gives 12/15= 0.8 • 100% = 80%

If she gets 80% of the next set of 25 questions right

25 • 0.8 = 20
She will get 20 problems correct.

12 is 80% of 15. So if the rate continues, She will answer 20 out of the 25 correctly. Hope I helped love! <3
