The larger your denominator, the smaller your overall answer.

Explanation:

All fractions are division problems. Doing the math

#3/7~~0.429#

#3/9~~0.333#

Thus #3/7"ths"# is greater since the overall unit (represented by the numerator) is divided into fewer pieces. The more pieces you divide a whole into, the smaller each individual piece becomes.

#3/7# is greater than #3/9#.

Explanation:

#3/7# and #3/9# have common denominator #7*9 = 63#

#3/7 = (3*9)/(7*9) = 27/63#

#3/9 = (3*7)/(9*7) = 21/63#

Since #27 > 21#, we see that #27/63 > 21/63#.

So #3/7 > 3/9#
