Form a common denominator. That means take 14/20 and change it into a number divided by 100. Since 20 x 5 = 100, multiply 14/20 by 5/5. 5/5 = 1, so we are keeping balance in the equation when we do this. Since 14 x 5 = 70, and 20 x 5 = 100,
14/20 = 70/100
Answer: 70/100
Sort the data from the smallest one.
42, 55, 69, 74, 78, 83, 83, 97, 99
There are 9 data, n = 9
Find the location of Q₂
Q₂ location = (n + 1)/2
Q₂ location = (9 + 1)/2
Q₂ location = 10/2
Q₂ location = 5
The location of Q₂ is in the fifth order
42 first order
55 second order
69 third order
74 fourth order
78 fifth order
etc
So the Q₂ or the median is 78
Hence, required answer is <u>3</u><u>3</u><u>6</u>

I was trying to solve, but im not sure since the box has three different sizes. Can you take a picture of the homework or no?
