Question

5/6 * (-0,7) - 5/42 * (-0,7) - 1/3 * (-0,7) - 4/7 * (-0,7) = Даю 15 баллов

Answer 1

5/6 * (-0,7) - 5/42 * (-0,7) - 1/3 * (-0,7) - 4/7 * (-0,7)=0,13333333333

Answer 2

To calculate the given expression, let's first simplify the fractions:

5/6 * (-0.7) = -0.58333... 5/42 * (-0.7) = -0.08333... 1/3 * (-0.7) = -0.23333... 4/7 * (-0.7) = -0.4

Now, substituting these values back into the expression:

-0.58333... - (-0.08333...) - (-0.23333...) - (-0.4)

Note: When subtracting a negative number, it becomes addition:

-0.58333 + 0.08333 + 0.23333 + 0.4

Adding these values:

-0.58333 + 0.08333 + 0.23333 + 0.4 = 0.13333...

Therefore, the result of the given expression is approximately 0.13333... or 0.133 (rounded to three decimal places).
