Nia answered correct answers = 80% of the 40 questions
When we remove % sign from a number, we divide that number by 100
= [tex] \frac{80}{100} [/tex] of 40
=[tex] \frac{80}{100} \times 40 [/tex]
Cancelling the two zeroes from numerator and denominator,
= [tex] 8 \times 4 [/tex]
= 32.
Total correct answers answered by Nia = 32
