Question

1)51,39-68,44:23,6+2,1= 2)(18,13-6,73)*(19,6:5,6)= Если можете решите пожалуйста в столбик или по действиям.

Answer 1

1) 68,44:23,6=2.9
2)51.39-2.9=48.49
3)48.49+2.1=50.59

Answer 2

1) To solve the expression 51.39 - 68.44 ÷ 23.6 + 2.1, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

Step 1: Perform the division 68.44 ÷ 23.6, which equals approximately 2.9. Step 2: Subtract 2.9 from 51.39, which equals approximately 48.49. Step 3: Add 2.1 to 48.49, which equals approximately 50.59.

Therefore, the result of the expression 51.39 - 68.44 ÷ 23.6 + 2.1 is approximately 50.59.

2) To solve the expression (18.13 - 6.73) * (19.6 ÷ 5.6), we again need to follow the order of operations.

Let's break down the expression step by step:

Step 1: Perform the subtraction 18.13 - 6.73, which equals approximately 11.4. Step 2: Perform the division 19.6 ÷ 5.6, which equals approximately 3.5. Step 3: Multiply 11.4 by 3.5, which equals approximately 39.9.

Therefore, the result of the expression (18.13 - 6.73) * (19.6 ÷ 5.6) is approximately 39.9.
