Write a fraction that is less than 5-6 and has a denominator of 8

We know that 5/6 is way more than 1/2 so we will be safe is we chose a fraction that has a denominator of 8 and is half or less

4/8, 3/8,2/8 and 1/8 are all safe bets and are less than 5/6
so is 5/8 because there is a rule that says is two fractions have the same numerator, the one with the smaller denominator is larger   5/6 > 5/8
Even 6/8 is smaller.  If you change it to a decimal 6/8 = 3/4 = .75  5/6 = .8333
.833..> .75 so we have lots of fractions we can write:
1/8,  2/8,  3/8,   4/8  5/8 and 6/8

7/8 is not because of different rule.  If the numerators and denominator of two fractions are the same distance apart the larger pair is greater.
Notice in 7/8, the 8 is one more than 7    and in 5/6, the 6 is one more than 5  (notice that the smaller number in each pair was in the numerator).  7/8>5/6
