To solve the expression (1-89/20):3/140, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

2. Next, we subtract 4.45 from 1: 1 - 4.45 = -3.45.

3. Now, we divide -3.45 by 3: -3.45 / 3 = -1.15.

4. Finally, we divide -1.15 by 140: -1.15 / 140 = -0.00821428571.

Therefore, the value of the expression (1-89/20):3/140 is approximately -0.00821428571.
