Explanation:

Think of the first number as a count of how many 1s 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=88. An improper fraction is simply a sum of both terms present in the mixed number.

So our improper fraction would be:

2+78

=288+78

=168+78

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

=16+78

=238

This cannot be reduced further.
