Answer:
3 1/2 or 3 test tubes
Step-by-step explanation:
1/4 = 2/8
It will exact fit 3 1/2, but if you need a whole number than 3.
Assume the smaller one is x, then the other ones will be x+2 and x+4
x(x+2) + 2 = 5(x+4)
x^2 + 2x - 5x - 18 = 0
-> x^2 - 3x - 18 = 0
-> (x-6)(x+3) = 0
-> x = 6 or -3, since x must be positive, then x = 6
So the numbers are: 6, 8, 10
