I have no idea by just looking at them, so I change the fractions to a common denominator by using a form of one. 45 is common here.

5*4/5*9 = 20/45

------

3*7/3*15 = 21/45

------

We see that 7/15 is just greater than 4/9.

A mathematical rhetorical device, but they are very close and you have to do it in your head to see which is larger here.
