1/2=4/8 so any fraction between 4/8 and 7/8 could work. This way, you can easily see that 5/8 and 6/8 are between 4/8 and 7/8. For 3/4, 12/16, and 10/16 however, I just made fractions that are equivalent to 5/8 and 6/8. So 3/4=6/8 because both the numerator and denominator were doubled. For 12/16, I did 6x2 and 8x2, so 12/16=6/8. Lastly, for 10/16 I did 5x2 and 8x2, so 10/16=5/8.
