Question

Dan got 45 out of 72 correct in his test. What fraction of the marks did he get wrong? Give your answer in its simplest form.

Answer 1

Answer:

total questions = 72

correct answers = 45

wrong answers = 72 - 45 = 27

fraction of marks he got wrong = $\frac{27}{72} = \frac{3}{8}$

Answer 2

Total Questions:72
Correct = 45
So Incorrect= 72-45= 27
So Incorrect Fraction=
$\frac{27}{72} \\ = \frac{27}{72} \div \frac{9}{9} \\ = \frac{3}{8}$
