(80-5)*2:10

To solve the expression \( (80 - 5) \times 2 : 10 \), we first need to clarify the use of the colon (:) which usually denotes division. So, we can rewrite the expression as:

\[ \frac{(80 - 5) \times 2}{10} \]

Now, let's calculate it step-by-step:

1. Calculate \( 80 - 5 \): \[ 80 - 5 = 75 \]

2. Multiply the result by 2: \[ 75 \times 2 = 150 \]

3. Divide by 10: \[ \frac{150}{10} = 15 \]

Thus, the final result is \( 15 \).
