Most methods deal with directly comparing the two fractions e.g by converting them to equivalent fractions and  then comparing the numerators.

But there is another way. Sometimes, it is easier to compare the complement. Let's say we want to compare two numbers A and B, instead of comparing A and B directly, we can compare their complements with respect to another number C. That is, compare C - A and C - B.

If C - A > C - B then we immediately know that A < B.

In this case, we compare the complements of 8/13 and 7/12 with respect to 1.

Let's compare 1 - 8/13 = 5/13 with 1 - 7/12  = 5/12.

Here, we can immediately see that 5/13 < 5/12 (Why? 1/13 < 1/12 therefore, 5*1/13 < 5*1/12)

Since 5/13 < 5/12, we immediately know that 8/13 > 7/12.

Divide the fraction \frac{8}{13} to get 0.6153.

Divide the fraction \frac{7}{12} to get 0.5834.

Compare the first digit after the decimal point.

Compare 0.6 and 0.5.

The number 0.6 > 0.5

So, \frac{8}{13} has a greater value and is bigger.
