1/2(2.5x)=40
2.5x=80
x=32
the number is 32
Well if she has 2 whole watermelons and 1/3 of one that would be 2 1/3 and that would be the mixed number and for the inproper fraction it would be 1 4/3 because you want to take out 1 from the 2 1/3 and add it on to the 1 of the 1/3 making it 1 and 4/3 I hope this helps!
Since this is a proportion, we cross multiply.
12/2=9/x (The variable "x" is used the represent the unknown number, and this is the number we are solving for)
12*x=2*9 (Cross multiply)
12x=18 (Simplify)
x=18/12 (Divide each side by 12)
x = 3/2 (Simplify fraction)
The unknown number is 3/2, or 1.5.

You could just use a calculator.
Answer:
33.4 m^3
Step-by-step explanation:
The edge length of the base is 1/4 of the perimeter, so is ...
(10.3 m)/4 = 2.575 m
Then the area of the base is the square of this, or ...
B = (2.575 m)^2 = 6.630625 m^2
The volume is ...
V = (1/3)Bh = (1/3)(6.630625 m^2)(15.1 m) ≈ 33.4 m^3
The volume of the pyramid is about 33.4 cubic meters.
