Answer:

x = 9

Explanation:

You want the value of x that satisfies 6/40 = x/60.

One-step equation

This equation can be solved in one step: multiply by the inverse of the coefficient of x.

The coefficient of x is 1/60. Its inverse is 60/1 = 60. Multiplying the equation by 60 gives ...

60(6/40) = 60(x/60)

360/40 = x

9 = x

__

Additional comment

Often, you will be advised to "cross multiply" as the first step in solving a proportion. Doing this would give you ...

6(60) = 40(x)

Now, you would need to divide by the coefficient of x (or multiply by its inverse).

6(60)/40 = (40x)/40

360/40 = x = 9

This accomplishes in two steps what we did above in one step.
