Answer:

#3 1/2#

Explanation:

First write it as a fraction:

let:

#m=3.5#

Multiply both sides by 10 to eliminate the decimal:

#10m = 35#

#m=35/10=7/2#

Now we make an improper fraction by dividing and finding the remainder:

#7/2 = 3 R 1#

Finally the improper fraction:

#3 1/2#

Just as a note mathematicians rarely use improper fractions as they are much harder to do operations on.
