Question

Mark got 54 out of 66 correct in his test. What fraction of the marks did he get wrong

Answer 1

Answer:

Step-by-step explanation:

Since Mark got 54 out of 66 correct on his test, we know that Mark had 66 questions on his test. 54 were correct. So, to find how many he got wrong we need to subtract 54 from 66. This gets you 12. Now to make the fraction for the number he got wrong. Make sure the number he got wrong is on the top and the number in total is on the bottom. Making your answer, 12/66.  Then you simplify by dividing both by 6 to get 2/11.

66-54= 12

Note: number on the bottom of the fraction is the denominator and number on top is the numerator.
