  4/9 > 5/12

Step-by-step explanation:

  4/9 = 16/36

  5/12 = 15/36

__

  16/36 > 15/36

  4/9 > 5/12

__

Additional comment

Above, we have use the least common denominator. The product 9×12 = 108 can also be used as a denominator. Then you can compare ...

  4/9×12/12 vs. 5/12×9/9

  48/108 vs 45/108

  4/9 > 5/12

Effectively, we're comparing the cross products: 4(12) vs 9(5).
