Question

3 2/7 * X = 1/7 Помогите пожалуйста, не понимаю как.

Answer 1

Ответ:

$x = \frac{1}{23}$

Пошаговое объяснение:

$3\frac{2}{7}x = \frac{1}{7};\\\\\frac{23}{7}x = \frac{1}{7};\\\\x = \frac{1}{7} : \frac{23}{7};\\\\x = \frac{1}{7} * \frac{7}{23};\\\\x = \frac{1}{23}$

Answer 2

Ответ:

$\dfrac{1}{23}$

Пошаговое объяснение:

3 2/7 * X = 1/7

$\displaystyle\\3\frac{2}{7}*x=\frac{1}{7} \\\\\frac{3\cdot7+2}{7} *x=\frac{1}{7} \\\\\frac{23}{7} *x=\frac{1}{7} \\\\x=\frac{1}{7} :\frac{23}{7} =\frac{1}{7}\cdot\frac{7}{23}=\frac{1}{23}$

Answer 3

Mathematical Expression: 3 + 2/7 * X = 1/7

To solve the equation 3 + 2/7 * X = 1/7, we need to isolate the variable X on one side of the equation.

Let's break down the steps to solve this equation:

Step 1: Subtract 3 from both sides of the equation to move the constant term to the right side: 3 + 2/7 * X - 3 = 1/7 - 3

Simplifying the left side: 2/7 * X = 1/7 - 3

Step 2: Simplify the right side of the equation: 1/7 - 3 = 1/7 - 21/7 = -20/7

So, the equation becomes: 2/7 * X = -20/7

Step 3: To isolate X, we need to multiply both sides of the equation by the reciprocal of 2/7, which is 7/2: (2/7 * X) * (7/2) = (-20/7) * (7/2)

Simplifying both sides: X = -20/2 = -10

Therefore, the solution to the equation 3 + 2/7 * X = 1/7 is X = -10.
