Question

-3,5*(-1/3):(-7,1-(-6,4))

Answer 1

-3,5× (-1/3):(-7,1-(-6,4)) = - 1 ²/₃
-3,5×(-¹/₃) = -³⁵/₁₀ × (-¹/₃) = ³⁵/₃₀ = ⁷/₆
(-7,1-(-6,4) =  -7,1 + 6,4  = - 0,7 = - ⁷/₁₀
⁷/₆ : (-⁷/₁₀) = ⁷/₆ × (-¹⁰/₇) = - ⁷ˣ¹⁰/₆ₓ₇ = - ¹⁰/₆ = - 1⁴/₆ = - 1²/₃

Answer 3

To solve the expression -3.5 * (-1/3) / (-7.1 - (-6.4)), let's break it down step by step:

First, let's simplify the numerator: -3.5 * (-1/3).

Multiplying -3.5 by -1/3 gives us: (-3.5) * (-1/3) = 3.5/3

Now, let's simplify the denominator: -7.1 - (-6.4).

The subtraction of -6.4 from -7.1 can be rewritten as the addition of 6.4 to -7.1: -7.1 - (-6.4) = -7.1 + 6.4 = -0.7

Now, let's substitute the simplified numerator and denominator back into the original expression:

(3.5/3) / (-0.7)

To divide by -0.7, we can multiply by the reciprocal: (3.5/3) * (-1/0.7)

Now, we can simplify further by multiplying the numerators and the denominators: (3.5 * -1) / (3 * 0.7)

This simplifies to: -3.5 / 2.1

Finally, dividing -3.5 by 2.1 gives us the result: -3.5 / 2.1 ≈ -1.6667

Therefore, the value of the expression -3.5 * (-1/3) / (-7.1 - (-6.4)) is approximately -1.6667.
