Solution: (Hide)
Take all proper fractions where the numerator and denominator are a single digit.
Exclude fractions that are not between 0 and 1.
Exclude fractions that can be further reduced (e.g. eliminate 6/8 since it can be reduced to 3/4).
Put the fractions in order according to increasing value.
Remove the "/" so the fraction appears as a 2 digit number.
