Answer:

720

Explanation:

We are looking for the difference between 2/3 and 1/2, which we know to be 120. To subtract fractions of different denominators, we need to find the common denominator (this can be found by finding the LCM of both denominators)

120 = 2/3 - 1/2 = 4/6 - 3/6
1/6 = 120

We can multiply 120 by 6 to find the value of the full bank.

1/1 = 720
