2*2*5*99:5

To solve the expression \( 2 \times 2 \times 5 \times \frac{99}{5} \), we can simplify it step by step.

1. First, calculate \( \frac{99}{5} = 19.8 \).
2. Now substitute that back into the expression: \( 2 \times 2 \times 5 \times 19.8 \).
3. Next, calculate \( 2 \times 2 = 4 \).
4. Then, multiply that by 5: \( 4 \times 5 = 20 \).
5. Finally, multiply by \( 19.8 \): \( 20 \times 19.8 = 396 \).

So, the final result of the expression \( 2 \times 2 \times 5 \times \frac{99}{5} \) is \( 396 \).
