0.28*19-0.4*2.8-(-280)-28*0.15 помагите решить пример

Answer 1

0,28*19-0,4*2,8-(-280)-28*0,15=280

Answer 2

To solve the given expression, let's break it down step by step:

1. Multiply 0.28 by 19: - 0.28 * 19 = 5.32

2. Multiply 0.4 by 2.8: - 0.4 * 2.8 = 1.12

3. Negate -280: - (-280) = 280

4. Multiply 28 by 0.15: - 28 * 0.15 = 4.2

Now, let's substitute the values we obtained into the original expression:

5. Substitute the values: - 5.32 - 1.12 - 280 - 4.2

6. Perform the subtraction and addition operations: - 5.32 - 1.12 - 280 - 4.2 = -280

Therefore, the value of the given expression is -280.
