Use the formula for percentages:
Part/Whole = % / 100
25/35 = x / 100 [Plug-in the values]
(25)(100) = (x)(35) [Cross-mulitiply]
2500 = 35x [Solve for x]
2500/35 = 35x / 35
71.428% = x
.
.
Check by plugging all of the variables back into the original formula:
Part/Whole = % / 100 [Formula for percentages]
25/35 = 71.428 / 100 [Plug-in all of the the values]
.71428 = .71428 [Checks out]
