Philip took a test and missed 38%of the questions. if he missed 28 questions, how many questions were in the test?
--------------
Let the number of questions be "x"::
------
Equation:
0.38x = 28
-----
x = 2800/38
-----
x = 73.68
----
Rounded up, x = 74 questions.

let x = no. of questions on the test
if he missed 38% that means got 100 - 38 = 62% right
%28%28x-28%29%29%2Fx = .62
multiply both sides by x
x - 28 = .62x
x - .62x = 28
.38x = 28
x = 28/.38
x = 74 questions

Check %28%2874-28%29%29%2F74 * 100 = .62 ~ 62% right (38% wrong)
