Question

(2р-3*4/15)*1,3=13/25

Answer 1

Ответ:

Пошаговое объяснение:

(2р - 3 * 4/15) * 1,3 = 13/25

(2р - 4/5) * 13/10 = 13/25

2р - 4/5 = 13/25 : 13/10

2р - 4/5 = 2/5

2р = 2/5 + 4/5

2р = 6/5

р = 6/5 : 2

р = 3/5

Answer 2

To solve the equation (2p - (3 * 4/15)) * 1.3 = 13/25, you can follow these steps:

1. First, simplify the expression inside the parentheses: 2p - (3 * 4/15) = 2p - (12/15)

2. Now, simplify the expression by finding a common denominator for 12/15 and 13/25. The common denominator is 75: (2p * 75/75) - (12/15 * 5/5) = (150p/75) - (60/75)

3. Simplify further by subtracting the fractions: (150p - 60) / 75 = 13/25

4. Now, you can set up the equation with a common denominator: (150p - 60) / 75 = 13/25

5. To get rid of the denominators, you can cross-multiply: 25 * (150p - 60) = 13 * 75

6. Simplify both sides of the equation: 3750p - 1500 = 975

7. Add 1500 to both sides to isolate the variable p: 3750p = 975 + 1500 3750p = 2475

8. Finally, divide both sides by 3750 to solve for p: p = 2475 / 3750

Now, you can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 75:

p = (33 * 75) / (50 * 75) p = 33/50

So, the solution to the equation is p = 33/50.
