Question

2/5х=1 7/15 решить уравнение

Answer 1

Ответ:

x= 5/11

Пошаговое объяснение:

2/5х=1 7/15

Приводим к общему знаменателю (15):

10/15x =1 7/15

Переводим 1 7/15 в неправильную дробь: 22/15

x= 22/15 : 10/15

x= 5/11

Answer 2

To solve the equation (2/5)x = 1, we need to isolate the variable x on one side of the equation. Here's the step-by-step solution:

Step 1: Get rid of the fraction in front of x by multiplying both sides of the equation by the reciprocal of 2/5, which is 5/2.

(5/2) * (2/5)x = (5/2) * 1

This simplifies to:

x = 5/2

Step 2: Convert the fraction 5/2 to a mixed number (if required):

5 divided by 2 is 2 with a remainder of 1, so the mixed number is 2 1/2.

Therefore, the solution to the equation is x = 2 1/2.
