Question

y and x are proportional. When x = 3/5 y = 1. What does x equal when y = 3/5 Enter your answer, as a simplified fraction, i​

Answer 1

When y and x are proportional, and given y = 3/5, the value of x is found by setting up a proportion based on the initial ratio x/y = 3/5 / 1. By cross multiplying, x is found to be 9/25.

Step-by-step explanation:

If y and x are proportional, and we know that when x = 3/5, y = 1, then we can set up a proportion to solve for x when y = 3/5. We use the initial ratio as a base for our proportion:

x/y = 3/5 / 1

Now we plug in the new value of y:

x/(3/5) = 3/5 / 1

To find x, we cross multiply:

x * 1 = (3/5) * (3/5)

x = 9/25

Therefore, the value of x when y = 3/5 is 9/25.
