Solve the math solution

Question

Solve the equation 3/x = 2/5. What is the value of x? Enter your answer as an integer, like this: 42 Or as a fraction, in simplest form, like this: 42/53.

Answer 1

Since your equation is a proportion, you can use the Cross-Products Property to cross-multiply and set the two products equal, so you will have 3(5) = 2(x). Divide both sides by 2 to isolate the x, and you have x = 15/2.
