To solve this expression, we start by simplifying the terms inside the parentheses first.

14(-6 1/3) = 14(-19/3) = -266/3

Now, we have:

1 18/25 - 9, 18 - 7, -266/3 : 5 1/3

Convert the mixed numbers to improper fractions:

1 18/25 = (25 * 1 + 18) / 25 = 43/25

9, 18 - 7 = 9 * 18 - 7 = 162 - 7 = 155

Now we have:

43/25 - 155, -266/3 : 5 1/3

Now we tackle the division:

-266 / 3 = -266 ÷ 3 = -266/3

Now we have:

43/25 - 155, -266/3 : 5 1/3

Next, let's subtract

43/25 - 155 = 43/25 - 155/1 = (431 - 15525) / 25 = (43 - 3875) / 25 = -3832/25

Finally, we have:

-3832/25, -266/3 : 5 1/3

To simplify even further, we divide -3832 by 25:

-3832 ÷ 25 = -153.28

So the final result is:

-153.28, -266/3 : 5 1/3
