Value of proportion Calculator a = bx/y [the factor of b cancels on the left side] y (a) = y (bx/y) [multiply by y on both sides] ay = bx [the factor of y cancels on the right side] Cross multiplication helps us to solve proportions by giving us an equation without fractions. The resulting equation is easier to solve. We need to isolate the dependent variable y y, we can do that by subtracting 2x 2x from both sides of the equation. Two Proportion Z-Test Calculator.
