Answer 1

1,35:2,7+6,02-5,9+0,4:2,5×(4,2-1,075)=0,5+6,02-5,9+0,16×3,125=0,5+6,02-5,9+0,5=1,12
Ответ: 1,12
P.s. рад был помочь.

Answer 2

Сначало выполняем действия в скобках, потом деление и умножение

1) 4,2-1,075=3.125
2)1,35/2,7=0,5
3)0,4/2,5=0,16
4)0,16×3.125=0,5
5)0,5+6,02=6,52
6)6,52-5,9=0,62
7)0,62+0,5=1.12

Answer 3

To solve this expression, we need to follow the standard order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

1. Parentheses: There are no parentheses in the expression.

2. Exponents: There are no exponents in the expression.

3. Multiplication and Division: We need to evaluate the expression inside the parentheses first.

   (4.2 - 1.075) = 3.125

   Then we need to multiply 3.125 by 0.4, which gives:

   0.4 * 3.125 = 1.25

   Now, we can evaluate the division in the expression:

   2.7 + 6.02 - 5.9 + (1.25 / 2.5)

   = 2.7 + 6.02 - 5.9 + 0.5

4. Addition and Subtraction: Finally, we can perform the addition and subtraction in the expression:

   2.7 + 6.02 - 5.9 + 0.5 = 3.32

Therefore, the value of the expression is 3.32.
