You need to use two concepts - 1)Writing percentages as decimals 2)Writing math sentences into algebraic sentences, or equations

33 1/3% = .3333... or 10/3 to be exact. So (10/3)x=65.2

That last part says that .3333 times some number, x, equals 65.2 which is the problem you want to solve, just put into an equation. Solve for x.
