Покрокове пояснення:

8,6 + 0,064 * 125 / 20 = 8,6 + 8/20 = 8,6 + 2/5 = 8,6 + 0,4 = 9,0

Answer 2

To solve the expression $8.6 + 0.064 \times \frac{125}{20}$, we follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). Here's the step-by-step calculation:

1. $125/20 = 6.25$
2. $0.064 \times 6.25 = 0.4$
3. $8.6 + 0.4 = 9$

So, $8.6 + 0.064 \times \frac{125}{20} = 9$.
