In order to solve this equation, what we can do is we can multiply both sides with C.
6c/15=2c/c
6c/15 = 2
If we multiply both sides with 15 we will have this:
(6c *15)/15 = 2 * 15
6c=30
Divide both sides with 6.
6c/6 = 30/6
c = 5

so we have this equation : 6/15=2/c
in this situation we can use something called the cross multiplication. In this case we can multiply the numerator of the first fraction with the denominator of the second fraction and that will be equal to the multiplication of the second fraction numerator with the denominator of the first fraction.
so: 6*c=15*2
6c=30
divide both sides by 6
6c/6=30/6
c=5
