Question

A student answered 38 problems on a test correctly and received a grade 95%. How many problems were on the test, if all the problems were worth the same number of points? (Round to the nearest whole number)

Answer 1

36 questions

Explanation:

the question can be rewritten to be:

what number out of 38 is equal to 95 percent

now you can use this ratio:

is/of = percent/100

x/38 = 95/100

cross-multiply to get:

100x = 38(95)

100x = 3610

x = 36.1
