Reduce the fraction: 5,040/59,400
clearly you can drop the trailing zeros, getting
504/5940
both are even, so you can factor out 2 top and bottom:
252/2970
and again: 126/1485
now 3's: 42/495
and again: 14/165
That's as far as you can go.
Or, you can factor both numbers.
5040 = 2^4 3^2 5 7
59400 = 2^3 3^3 5^2 11
Now you can cancel the common factors, leaving
(2*7)/(3*5*11) = 14/165
