To figure out which airline provides more reliable service, we need to figure out what ABC Airlines's delays are in percents.

To get that, we need to reduce 18/126 by 2.

When we reduce both the numerator and the denominator we get 9/63.

Now, we cannot reduce that again, without getting a decimal for the numerator/denominator.

So, now that we know that the fraction is 9/63, we divide it, and we get:

0.142857

Changing that into a percent, we get 14%.

14% is the percent that ABC Airlines has delays.

DEF Airlines has delays of 13% in recent flights.

So, from that, we can conclude that DEF gives more reliable service.
