Answer:
The math exam.
Step-by-step explanation:
Ir order to compare all these scores, let's convert them to the relative form (a percentage).
Art one is easy, since it's given by the problem: 78%.
English score percentage will be given by this operation: (19/25)=0.76= 76%.
Math is the same concept as in English, 32/40= 0.8= 80%.
Now, compare the 3 results:
Art: 78%.
English: 76%.
Math: 80%.
The math exam was was the one where Maria received the highest score out of the 3 tests.
