Grace scored 17 ot of 20 on her reading quiz and 20 out of 25 on her science quiz. on which quiz did grace score a higher percentage? show your work

Her reading quiz, because in order to find a percent dive 17 by 20 (or 20 by 25) and multiply the answer by 100.

Grace scored a higher percentage on her reading quiz because she only missed 3 problems and on her science quiz she missed 5
lets check-

proportion-20*5=100
17*5=85
25*4=100
20*4=80

85%-reading
80%- on math

so yes she did get a higher percentage on her reading quiz than on her science quiz

hope this helps
