If Luna casted 2020 spells, Ginny casted 2525 spells.

Step-by-step explanation:

The ratio that we have is

Luna: 4

Ginny: 5

This means that for each 4 spells that luna casts, Ginny cast 5 spells.

Now, we know that luna casted 2020 spells, now, how many groups of 4 e have here?

2020/4 = 505

This means that Luna casted froups of 4 spells 505 times, and for each of those groups, Ginny casted 5 spells, so Ginny casted:

5*505 = 2525 spells.
