Calculate 4.25 Divided by 2.5 Multiplied by 9.9 Minus 0.17

To solve this expression, we follow the order of operations (PEMDAS/BODMAS):

4.25 / 2.5 * 9.9 - 0.17

First, perform the division: 4.25 / 2.5 = 1.7

Now we have: 1.7 * 9.9 - 0.17

Next, perform the multiplication: 1.7 * 9.9 = 16.83

Now we have: 16.83 - 0.17

Finally, subtract: 16.83 - 0.17 = 16.66

Therefore, the value of the expression 4.25/2.5*9.9-0.17 is 16.66.
