3/3:(80-6)

To solve this expression, we need to follow the order of operations (also known as PEMDAS/BODMAS):

1. Parentheses: Start by evaluating what's inside the parentheses. (80 - 6) = 74

2. Division: Divide the result from step 1 by 3. 74 ÷ 3 = 24.67 (rounded to two decimal places)

So, 3/3:(80-6) equals approximately 24.67.
