a/b = c/d cross multiplies to a*d = b*c

What is the first step that you have to do in order to solve the proportion: 1/3=y/26 A. 8.5 B. 26y = 3 C. y = 3(26) D. 3(y) = 1(26) I got B!:)

B is incorrect

a/b = c/d cross multiplies to a*d = b*c

good, you got it, so that's close to 3(y) = 1(26) you just have to factor and flip the equation
