First find the common denominator.
7/8 and 8/9 = 63/72 and 64/72

here is a simple way to compare fractions
Write them down side by side, leave a space between them.
7/8 8/9
crossmultiply
first :topleft times bottom right
second: bottomleft times top right
so
63 64
what symbol between the 63 and 64 would make a true statement ?
63 < 64
put that same symbol between the original fractions.
of course if you have a calculator, just change each fraction to a decimal, then it easy to decide which is the smaller
7/8 = .875
8/9 = .88888..
since .875 < .8888.
7/8 < 8/9
