#=>23/8#

Explanation:

Think of the first number as a count of how many #1#s you have. You can express #1# as a fraction where the numerator and denominator are equal. In this case, it would useful to use #1=8/8#. An improper fraction is simply a sum of both terms present in the mixed number.

So our improper fraction would be:

#2 + 7/8#

#=2*8/8 + 7/8#

#=16/8 + 7/8#

We have a common denominator, we can combine the fractions:

#=(16+7)/8#

#=23/8#

This cannot be reduced further.
