Answer:
8 and 2
Step-by-step explanation:
Let x = the smaller number.
Let y = the larger number.
Let the numbers be x and y
x+y = 10 ..............(1)
y= 4x ........(2)
Put value of y into equation 1
x + y = 10
4x + x = 10
5x = 10
Divide both sides by 5
x = 10/5 = 2
Put value of y into equation 2
y= 4x
y= 4(2)
y = 8
Therefore the numbers are 8 and 2

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.
