Answer:
<h2>x = 1/8</h2>Step-by-step explanation:
Given the expression 0.25÷3=x÷1 1/2, we are to look for the value of x from the given equation. Rewriting the equation we will have;
On simplification;
Hence the value of x in the expression is 1/8
From the pool of 5 letters, we're picking 4. We can arrange the 4 we picked in 
ways.
But there are 5 ways of *not* picking the remaining letter. To account for the arrangements containing the letter not picked, we multiply this total by 5.
Put another way, suppose we drew a, b, c, and d, but not e. We have 24 possible arrangements for these 4 letters, but for any distinct arrangement there are 5 ways of replacing any letter with e.
So the number of arrangements we can actually make is
.

There are many ways. 
is actually the same as 
so anything you do just has to have a numerator exactly half as the denominator. So one that would work is 
I just doubled both numbers. Other ones would be 
all of which the numerator is exactly half the denominator.
