Find two fractions between 2/5 and 3/5 plot on number line

9/15 10/15 then make the denominators smaller

18/30 20/30 make them smaller again

36/60 40/60 I will start here, and show you how to get it:

37/60, 38/60, 39/60 and if you simplify:

37/60, 19/30, 13/20 are between 3/5 and 2/3

If you need more than that, you would need to continue to make the denominators smaller.
