Question

. A student answered 48 problems on a test correctly and received a grade of 75%. How many problems were on the test, if all the problems were worth the same

Answer 1

75% = 48
divide by 75 both sides

1% = 0.64
multiply by 100 both sides

100% = 64 problems (ofc this only works if the problems are with the same, in this case it is)
