Answer:
85%
Step-by-step explanation:
Johny answered [tex]\frac{17}{20}[/tex] questions correctly. To change this into percent, just multiply both the numerator and denominator by the number that makes the denominator equal 100. In this case, 5 would make 20 equal 100, so we multiply both the top and bottom by 5.
[tex]\frac{17}{20} *\frac{5}{5}=\frac{85}{100}[/tex]
Your numerator will be your percentage if the denominator is 100.
