Question

36 / 4 x равно 27 / 15

Answer 1

Сначала найди область недопустимых значений, в этом случае x не равно 0.
Потом сократи дроби;
Получается: 9/x=9/5;
Когда числители одинаковы, приравнивай знаменатели: x=5,x не равно 0
Ответ: x=5

Answer 2

To solve the equation, you need to perform the operations in the correct order, following the standard rules of arithmetic (PEMDAS/BODMAS). The order of operations is as follows:

1. Parentheses (Brackets)
2. Exponents (Orders)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve the equation step by step:

1. 36 / 4 = 9
2. 9 x (unknown) = 27 / 15

To find the value of the unknown, we can rewrite the second part as follows:

3. 27 / 15 = 9 / 5

Now, we have:

4. 9 x (unknown) = 9 / 5

To find the value of the unknown, divide both sides by 9:

5. (unknown) = (9 / 5) / 9

Now, performing the division:

6. (unknown) = 9 / 5 * 1/9

Next, simplify the expression:

7. (unknown) = 1 / 5

So, the solution to the equation is:

36 / 4 = 1 / 5
