Answer:
The answer would be {(12* 3)*5]
Explanation:
Since all of the numbers in your equation are being multiplied together, they can be in any order and still equal the same amount.
If you solve {(5 * 3)*12], you'll get 180 by doing 5*3*12.
An example of reordering it would be: {(12* 3)*5]
(12*3*5 = equals 180, like the original equation)
