Answer: 1/7
Step-by-step explanation:
Total questions answered = 49
Harry correct answers = 42
Harry wrong answers = (49 - 42) = 7
Thus, the only fraction of wrong answers = (Number of wrong answers / Total number of questions answered)
i.e 7/49
= 1/7
Thus, harry answered 1/7 of the 49 questions wrongly.
You'll have to multiply 0.7 by 120.
120*0.7 = n
n is the number that is 70% of 120
120 * 0.7 = 84
