Question

1 1/3x +0,2 =1 3/25y-1,2=1,2=0,6

Answer 1

1 1/3х + 0,2 = 1
1 1/3х = 1 - 0,2
1 1/3х = 0,8
4/3х = 0,8
х = 8/10 : 4/3
х = 6/10
х = 0,6

Answer 2

To solve the given equations, let's work on them one by one:

Equation 1: 1 1/3x + 0.2 = 1

To simplify this equation, let's convert the mixed fraction to an improper fraction:

1 1/3x = 4/3x

Now, we can rewrite the equation as:

4/3x + 0.2 = 1

Subtracting 0.2 from both sides, we have:

4/3x = 1 - 0.2 4/3x = 0.8

To solve for x, we multiply both sides by 3/4:

(3/4) * (4/3x) = (3/4) * 0.8

The 4/3 and 3/4 cancel each other out, leaving us with:

x = 0.8 * (3/4) x = 0.6

Therefore, the solution for Equation 1 is x = 0.6.

Equation 2: 1 3/25y - 1.2 = 1.2 - 0.6

First, let's simplify the left side of the equation:

1 3/25y = 28/25y

Now, we can rewrite the equation as:

28/25y - 1.2 = 0.6

Adding 1.2 to both sides, we get:

28/25y = 0.6 + 1.2 28/25y = 1.8

To solve for y, we multiply both sides by 25/28:

(25/28) * (28/25y) = (25/28) * 1.8

The 28/25 and 25/28 cancel each other out, leaving us with:

y = 1.8 * (25/28) y = 1.6071428571428572

Therefore, the solution for Equation 2 is y ≈ 1.607.

In summary: Equation 1: x = 0.6 Equation 2: y ≈ 1.607
