We just multiply the two values so:
[tex]20* \frac{85}{100} = 20*\frac{13}{20} =13[/tex]

Therefore Joan answered 13 of the questions correctly

To find how many problems she answered correctly, just multiply 20 by 85%

20 x 85%(or simply 0.85)=17 problems

Therefore she answered 17 problems correctly and 3 of them are incorrect. Hope this helps =)
