А) 2/14=х/7

To solve the equation, we can use cross multiplication.

First, we multiply the numerator of the left side by the denominator of the right side, and vice versa.

2 * 7 = 14 * x

14 = 14x

Next, we can divide both sides of the equation by 14 to solve for x:

14/14 = 14x/14

1 = x

Therefore, the solution to the equation 2/14 = x/7 is x = 1.
