Answer: a)[tex]\frac{68}{80}[/tex]

b)85%

c)0.85


Step-by-step explanation:

Given : Justine answered 68 questions correctly on an 80 questions test .

Thus, Total answers = 80

Correct answers= 68

In fraction,

[tex]\frac{\text{correct answers}}{\text{total answers}}=\frac{68}{80}[/tex]

On dividing both numerator and denominator by 4, we get fraction in simplest form

[tex]\frac{17}{20}[/tex]

To convert in decimal divide 17 by 20 , we get 0.85

To convert in percent multiply 100 to the decimal, we get 85%
