Answer:
0.25
Step-by-step explanation:
First...
Assume that the number is <em>x </em>and make an equation.
(<em>x</em> + <em>x</em>) 8 = 4
Next...
Add.
(2<em>x</em>) 8 = 4
After that...
Divide.
2<em>x</em> = 4/8 so 2<em>x</em> = 1/2
Finally...
Divide more
<em>x</em> = 1/4 or 0.25
So your answer is 0.25.
