Answer 2

Ответ:

12,03

Пошаговое объяснение:

1,8×(5,9 - 2  11/20)+(1/2+0,28)÷0,13=1.8(5.9-51/20)+(1/2+0.28)÷0.13= 1.8(5.9-2.55)+(0.5+0.28)÷0,13= 1.8·3.35+0.78÷0,13=6.03+6=12,03

Answer 3

To solve this expression, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction):

1. First, we need to subtract 2 and 11/20 from 5.9: 5.9 - 2 - 11/20 = 3.4
2. Next, we need to multiply 1.8 by 3.4: 1.8 x 3.4 = 6.12
3. Now we need to evaluate the expression in the parentheses and add it to the previous result: 6.12 + (1/2 + 0.28) ÷ 0.13 We can simplify 1/2 + 0.28 by finding a common denominator of 2: 1/2 + 0.28 = 1/2 + 0.56/2 = 1.56/2 Now we can rewrite the expression as: 6.12 + 1.56/2 ÷ 0.13
4. Next, we need to perform the division in the parentheses: 1.56/2 ÷ 0.13 = 0.6
5. Finally, we can add this result to the previous one: 6.12 + 0.6 = 6.72

Therefore, the final answer is 6.72.
