Question

7,2•3,8+(3,24-2,1312):0,42=?​

Answer 1

Ответ:

30

Пошаговое объяснение:

7.2*3.8+(3.24-2.1312):0.42=30

1) (3.24-2.1312)=1.1088

2) 1.1088:0.42=2.64

3) 7.2*3.8=27.36

4) 27.36+2.64=30

Answer 2

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS) to evaluate it step by step:

Step 1: Perform the subtraction inside the parentheses.

3.24 - 2.1312 = 1.1088

Now the expression becomes:

7.2 * 3.8 + (1.1088) / 0.42

Step 2: Divide 1.1088 by 0.42.

1.1088 / 0.42 ≈ 2.640

Now the expression becomes:

7.2 * 3.8 + 2.640

Step 3: Multiply 7.2 by 3.8.

7.2 * 3.8 = 27.36

Now the expression becomes:

27.36 + 2.640

Step 4: Add 27.36 and 2.640.

27.36 + 2.640 = 29.999999999999996 (approximately 30)

Therefore, the result of the expression 7.2 * 3.8 + (3.24 - 2.1312) / 0.42 is approximately 30.
