Question

1 2/5 × (-2 1/7) × 1/6 × x = 4 1/2 × 17/18 × 1 2/34

Answer 1

Ответ:

Пошаговое объяснение:

7/5 * (-15/7) * 1/6х = 9/2 * 17/18 * 36/34

-15/5 * 1/6х = 9/2 * 1/1 * 2/2

-15/30х = 18/4

-1/2х = 9/2

х = 9/2 : (-1/2)

х = 9/2 * (-2/1)

х = -18/2

х = -9

Answer 2

To solve this equation, you need to find the value of x. Let's break it down step by step.

1. Start with the left side of the equation:

(1 2/5) × (-2 1/7) × (1/6) × x

First, convert all mixed numbers to improper fractions:

(7/5) × (-15/7) × (1/6) × x

2. Now, multiply the fractions:

(7/5) × (-15/7) × (1/6) × x = (-105/210) × x = (-1/2) × x

3. Next, simplify the right side of the equation:

(4 1/2) × (17/18) × (1 2/34)

Convert the mixed numbers to improper fractions:

(9/2) × (17/18) × (36/34)

4. Multiply the fractions on the right side:

(9/2) × (17/18) × (36/34) = (153/68)

5. Now, you can set up the equation:

(-1/2) × x = 153/68

6. To isolate x, divide both sides of the equation by (-1/2):

x = (153/68) / (-1/2)

To divide by a fraction, multiply by its reciprocal:

x = (153/68) × (-2/1)

x = -306/68

7. Finally, simplify the fraction:

x = -153/34

So, the solution to the equation is:

x = -153/34
