Think of it this way:

There is a number x, that, when we divide by 13/19 equals 133 / 65
Putting this into an equation gives us

x / 13/19 = 133/65
(division sign doesn't come through - so i have / instead.)

Multiply both sides by 13/19 and the fraction on the left will go away

x = 133/65 * 13/19
133 is 19 * 7 so the 19 will cancel and leave you with
(7/65) * 13
65 is 13 * 5, so the 13's cancel
leaving us with
7/5
