To compare fractions, either change to a decimal or use a common denominator.

So,

5/16=5*9/(16*9)=45/144
7/18=7*8/(18*8)=56/144

5/15 equals 0.3125
7/18 equals 0.388888

So, 7/18 is the greater of the two numbers.

5/16 * (18/18) = 90/288
7/18 * (16/16) = 112/288

The second one is bigger.

Note that I have multiplied by 1 in both cases (multiplying by 1 does not change the value).
