Answer:
The fraction is [tex]\frac{1}{4}[/tex].
Step-by-step explanation:
Eduardo Is thinking of a non-unit fraction with a single-digit denominator.
Assuming the fraction to be [tex]\frac{1}{x}[/tex].
When Eduardo multiplies his fraction by 5 he gets a mixed number and when he multiplies his fraction by 3 he can simplify the answer.
Therefore, the fraction chosen by Eduardo will be [tex]\frac{1}{x}[/tex], where x is between 5 and 3.
So, the fraction is [tex]\frac{1}{4}[/tex].
Again, when he multiplies his fraction by 4 he gets [tex](\frac{1}{4} \times 4) = 1[/tex] which is a whole number. (Answer)
