Solution

Finding the proper fractions

A fraction is known as a proper fraction if its numerator is less than the denominator.

Here, the proper fraction has to be made such that:

1) Numerator < denominator

2) Numerator + denominator =10

Now, 19 is a fraction such that

1) 1<9

2) 1+9=10.

Therefore, 19 is the required proper fraction.

The other fractions which satisfy the above two conditions are 28,37 and 46.

Hence, there are only four proper rational fractions with the sum of numerator and denominator as 10.
