Question

(3,09:1/40-32,3:17\50)•1/4+0,069•1/3

Answer 1

(309/5*2-19*5)*1/4+69/1000*1/3

(618/5-95)*1/4+23/1000

143/5*1/4+23/1000

143/20+23/1000

7173/1000=7 173/1000~7,173

Answer 2

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve it step by step:

Step 1: Deal with the parentheses and brackets. (3,09:1/40 - 32,3:17\50) • 1/4 + 0,069 • 1/3 Convert the decimal separators from comma to period for consistency. (3.09:1/40 - 32.3:17\50) • 1/4 + 0.069 • 1/3

Step 2: Perform the operations inside the parentheses and brackets. 3.09:1/40 means 3.09 divided by (1/40). 32.3:17\50 means 32.3 divided by (17/50).

3.09 ÷ (1/40) = 3.09 * 40 = 123.6 32.3 ÷ (17/50) = 32.3 * (50/17) ≈ 94.70588235294117

The expression now becomes: (123.6 - 94.70588235294117) • 1/4 + 0.069 • 1/3

Step 3: Perform the remaining multiplications and divisions. 123.6 - 94.70588235294117 ≈ 28.89411764705883

(28.89411764705883) • 1/4 ≈ 7.223529411764706

0.069 • 1/3 ≈ 0.023

Step 4: Perform the addition. 7.223529411764706 + 0.023 ≈ 7.246529411764706

So, the final result is approximately 7.2465.
