Define the two numbers
-----------------------------------------------------------
Let the first number be x.
Let the second number be y.
------------------------------------------------------------
Form equations and solve x and y
------------------------------------------------------------
x + 2y = 14 ------------------ (1)
2x + y = 31 ------------------ (2)
------------------------------------------------------------
Equation (1) x 2
------------------------------------------------------------
2x + 4y = 28 ---------------(1a)
------------------------------------------------------------
Equation (1a) - 2
------------------------------------------------------------
3y = 28 - 31
3y = -3
y = -1
------------------------------------------------------------
Substitute y = -1 into (1)
------------------------------------------------------------
x + 2(-1) = 14
x -2 = 14
x = 14 + 2
x = 16
------------------------------------------------------------
Answer: x =16, y = -1

You simply divide 6 by 4 that will get you a answer of 1.5
I hope this help you have a nice day.
Irrational numbers are numbers that can not be written as a simple fraction. An example of one would be 
. Pi is about 3.14, but it goes on forever. You can not write pi as a simple fraction.
