Let's write an equation describing the problem.
Any even whole number may be represented by writing

in which

is any non-negative integer.
It follows that for a even whole number

the next (consecutive) even whole number can be written as

.
We now need to solve the following equation:

If we solve for

we get:

We have to values, as the equation is quadratic. We take the positive one as the correct one. So

, and if we plug in this value to

and

we know that the
asnwer is 16 and 18.
Answer: <em><u>1/9, 0.48, 0.6, 2/3, 5/6</u></em>
Step-by-step explanation:
Order these numbers: 0.6 , 2/3 , 5/6 , 1/9 , 0.48
0.6 = 0.6
2/3 = 0.6666666....
5/6 = 0.8333333....
1/9 = 0.111111.....
0.48 = 0.48
In order, it will go 1/9, 0.48, 0.6, 2/3, 5/6
Only the top one is yes other 3 are no
