Question

РЕШИТЕ уровнение: 1)x:6/7=7/6:7/2 ответ: 2)4,5:(3x)=4:12 ответ: 3)1/5=2:(3x) ответ: помогите плиз

Answer 1

1)
х:6/7=7/6:7/2
7/2*х=6/7*7/6
7/2*х=1
х=1:7/2
х=2/7

2)
4,5:(3х)=4:12
4*3х=4,5*12
12х=4,5*12
х=4,5*12:12
х=4,5

3)
1/5=2:3х
3х=5*2
3х=10
х=10:3
х=3 1/3

Answer 2

1)x / 6/7=7/6 / 7/2
x * 7/2 =7/6*6/7 
7/2*x=1
x=1/ 7/2
x=2/7
2)4/12=1/3
4,5/3x=1/3
1.5/x=1/3
x=15/10 / 1/3
x=15/10*3/1
x=4.5
3)1/5=2/3x
3x=2 / 1/5
3x=10
x=10/3
x=3.33

Answer 3

Solving the Equations

1) To solve the equation x:6/7=7/6:7/2:

First, let's simplify the right-hand side of the equation: - 7/6:7/2 can be rewritten as (7/6)/(7/2), which simplifies to (7/6)*(2/7).

Now, the equation becomes: - x:6/7 = (7/6)*(2/7)

To solve for x, we can multiply both sides of the equation by 6/7: - x = (7/6)*(2/7)*(6/7)

Let's calculate the value of x using the given equation.

2) To solve the equation 4,5:(3x)=4:12:

First, let's rewrite the equation using the proper mathematical notation: - 4.5 / (3x) = 4 / 12

Now, we can solve for x by cross-multiplying and then isolating x.

3) To solve the equation 1/5 = 2 / (3x):

We can start by isolating the variable x. Multiply both sides of the equation by (3x) to get rid of the fraction on the right-hand side, and then solve for x.

Let's solve these equations step by step and find the answers.
