Well if there are 85 questions and 20% of them are correct, basically 20% means 20/100 which when reduced is equivalent to 1/5. so then you would take 85 and multiply it by 1/5 to get 17. He got 17 questions correct

85 x .20 = 17

or

20% = 20/100 = 2/10 =1/5
85 x 1/5 = 17

He got 17 problems correct.

I showed you two different ways to get the same answer one with a fraction and one with a decimal. I think doing percentages as decimals is easier but thats just me.
