Question

If Christina got 37 out of 40 or (37)/(40) questions on her math test correc. and 18 out of 20 or (18)/(20) ques on her science test correct, which test did she do better on?

Answer 1

She did better on her math test

Explanation:

18/20=36/40 which is her score on her science test

37/40 is her score on her math test

37/40>36/40 so she did better on her math test

You can also convert them into percentages:

Science test=18/20=9/10=90%

Math test=37/40=37*2.5/100=92.5%

92.5%>90%
