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

From 1/1 we know that that is still greater than 5/6, and doesn't have  as a denominator, but it is still a good place to start. Each time we can take away half until we get to something with a denominator of 8, which would take 1/1 to 1/2 and 1/2 to 1/4 and 1/4 to 1/8 1/8 is less than 5/6 and its denominator is 8.

1/8

5/6 as a decimal is around 0.83. (You get the decimal by dividing the numerator by the denominator)

2/8 as a decimal is 0.25. This number is less than 0.83.

1/8
2/8
3/8
4/8
5/8
6/8

Are all less than 5/6.
