Answer:
39.5
Step-by-step explanation:
We put the numbers in order least to greatest and pick the middle one because that number is the median:
36, 38, 39, 39, 40, 47, 48, 51
Since 39 and 40 are tied for the median we go in between those two numbers, 39.5. The answer is 39.5.

Answer:
7/4 + 9/-5 =
Since the denominator of the second fraction is negative the sign will change from negative to positive
We will get
7/4 - 9/5
First find the LCM
LCM of 4 and 5 is 20
7/4 - 9/5 = 5(7) - 4(9)/ 20
Simplify
We get
35 - 36/20
= -1/20
