(0.5,0.5)
Step-by-step explanation:
use the midpoint formula x1+x2/2 and y1+y2/2
Answer:
The fraction is 
Step-by-step explanation:
= 
Where x and y are the numerator and denominator of our new fraction respectively.
Also given is that x + y = 24
So
= 36 ÷ 60 = 0.6
x = 0.6y
Substituting x in x + y = 24 gives;
0.6y + y = 24 , 1.6y = 24
y = 24 ÷ 1.6 = 15
x = 24 - 15 = 9
So our fraction is 
Equals to -17
add the two negatives together
The water bill was 1/5 of the total, so was 0.2*$540 = $108.
