2,5:x=3 1/3 ÷1,2 Пжпжпжпжпжпж

Answer 1

Ответ:

Пошаговое объяснение:

2 5/10 : х = 3 1/3 : 1 2/10

25/10 : х = 10/3 : 12/10

25/10 : х = 10/3 * 10/12

25/10 : х = 100/36

х = 25/10 : 100/36

х = 25/10 * 36/100

х = 1/5 * 18/4

х = 18/20

х = 9/10

Answer 2

It seems like you're trying to solve an equation with fractions. Let's break down the equation and solve it step by step:

The equation you provided is: 2.5x = 3 1/3 ÷ 1.2

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

3 1/3 is the same as 10/3 in improper fraction form. So, we have: 2.5x = (10/3) ÷ 1.2

Now, let's divide 10/3 by 1.2: (10/3) ÷ 1.2 = (10/3) ÷ (12/10) = (10/3) * (10/12)

Now, multiply the fractions: (10/3) * (10/12) = (10 * 10) / (3 * 12) = 100/36

Next, simplify the fraction 100/36 by dividing both the numerator and denominator by their greatest common divisor, which is 4: (100/4) / (36/4) = 25/9

So, the equation becomes: 2.5x = 25/9

Now, to solve for x, divide both sides of the equation by 2.5: (2.5x) / 2.5 = (25/9) / 2.5

x = (25/9) / 2.5

To divide a fraction by a number, you can multiply the fraction by the reciprocal of that number (i.e., flip the number and put it in the denominator):

x = (25/9) * (1/2.5)

Now, multiply the fractions:

x = (25/9) * (2/5)

x = (25 * 2) / (9 * 5)

x = 50/45

Finally, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 5:

x = (50/5) / (45/5)

x = 10/9

So, the solution to the equation is x = 10/9.
