((3,2+0,32):0,1-(50-7,2)·0,1)·100

First, we simplify the expression inside the parentheses:
3.2 + 0.32 = 3.52
50 - 7.2 = 42.8
0.1 * 42.8 = 4.28

Now, we substitute these values back into the original expression:
((3, 4.28)/0.1)·100
= (3.52/4.28)·100
= 0.82243·100
= 82.243

Therefore, the solution to the expression is 82.243.
