Worked Solution & Example Answer:In a quiz, Darcy answered 16 of the 20 questions correctly - OCR - GCSE Maths - Question 6 - 2021 - Paper 1
Step 1
What fraction of the questions did Darcy answer correctly?
Answer
To find the fraction of questions that Darcy answered correctly, we can use the formula:
ext{Fraction} = rac{ ext{Correct Answers}}{ ext{Total Questions}} = rac{16}{20}Next, we simplify the fraction to its lowest terms. The greatest common divisor (GCD) of 16 and 20 is 4.
Dividing both the numerator and the denominator by 4, we get:
rac{16 ext{ (divided by 4)}}{20 ext{ (divided by 4)}} = rac{4}{5}Thus, the fraction of questions Darcy answered correctly is ( \frac{4}{5} ).
