Question

3 1/7 : (-x) = -6 2/7 : (-1) помогите пожалуйста

Answer 1

Ответ:

$3 \frac{1}{7} \div ( - x) = - 6 \frac{2}{7} \div ( - 1) = \\ 3 \frac{1}{7 } \div ( - x) = 6 \frac{2}{7} \\ ( - x) =3 \frac{1}{7} \div 6 \frac{2}{7} \\ ( - x) = \frac{22}{7} \div \frac{44}{7} \\ ( - x) = \frac{22}{7} \times \frac{7}{44} \\ ( - x) = \frac{1}{2} \\ ( - x) = 0.5 \\ x = - 0.5$

Answer 2

Solving the Equation 3 + 1/7 : (-x) = -6 2/7 : (-1)

To solve the equation 3 + 1/7 : (-x) = -6 2/7 : (-1), we can follow these steps:

1. Convert Mixed Numbers to Improper Fractions: - Convert the mixed numbers to improper fractions to simplify the equation.

2. Solve for x: - Once the equation is simplified, solve for the variable x.

Conversion of Mixed Numbers to Improper Fractions

The given equation can be rewritten as:

3 + 1/7 : (-x) = -6 2/7 : (-1)

First, convert the mixed numbers to improper fractions:

3 + 1/7 = (3 * 7 + 1) / 7 = 22 / 7

-6 2/7 = -6 + 2/7 = -6 * 7/7 + 2/7 = -44/7 + 2/7 = -42/7

The equation becomes:

22/7 : (-x) = -42/7 : (-1)

Solving for x

To solve for x, we can cross multiply and solve for x:

22/7 * (-1) = -42/7 * (-x)

-22/7 = 42/7x

Now, solve for x:

42/7x = -22/7

x = -22/7 / 42/7 x = -22/7 * 7/42 x = -22/42 x = -11/21

So, the solution to the equation 3 + 1/7 : (-x) = -6 2/7 : (-1) is x = -11/21.
