2/3=n/72

3n=144
144/3=48
48

Right.

that is correct also

To solve the equation 2/3 = n/72, you need to cross-multiply and solve for n.

First, multiply both sides of the equation by 72 to get rid of the denominator:
(2/3) * 72 = (n/72) * 72
48 = n

Now, to solve the equation 3n = 144, divide both sides of the equation by 3 to isolate n:
3n / 3 = 144 / 3
n = 48

Therefore, the value of n is 48.
