Answer
x=10
Work Step by Step
In order to solve for x in the equation $\frac{2}{3}$=$\frac{x}{15}$ we will apply the Cross Products Property of a Proportion that says that if
$\frac{a}{b}$=$\frac{c}{d}$, where b$\ne$0 and d$\ne$0, then ad=bc. If we set a=2, b=3, c=x, and d=15, then we'll apply this property.
(2)(15)=(x)(3)
30=3x
Then, to solve for x, we'll divide by 3 on both sides of the equation
$\frac{30}{3}$=$\frac{3x}{3}$
x=10
