Question

(-3,7 - 2,4) - (7/15 - 2/3) + 5,9 = -6,1 - (7/15 - 10/15) + 5,9 = -6,1 + 3/15 + 5,9 = -6.1 + 0,2 + 5,9 = 0 обьясните откуда берётся -6.1

Answer 1

-3,7-2,4=(-3,7)+(-2,4)=-6,1

Answer 2

Calculation Breakdown

To solve the given expression (-3.7 + -2.4) - (7/15 + 2/3) + 5.9, we can break it down step by step:

1. (-3.7 + -2.4): - The sum of -3.7 and -2.4 is -6.1.

2. (7/15 + 2/3): - The sum of 7/15 and 2/3 is 3/15.

3. -6.1 - (7/15 + 2/3) + 5.9: - Substituting the values calculated above, we get: -6.1 + 3/15 + 5.9.

4. -6.1 + 3/15 + 5.9: - The sum of -6.1 and 3/15 is -6.1 + 0.2. - Finally, the sum of -6.1 and 0.2 is -5.9.

Result

The result of the given expression (-3.7 + -2.4) - (7/15 + 2/3) + 5.9 is -5.9.

The value -6.1 arises from the initial calculation of (-3.7 + -2.4), which equals -6.1.
