If $\displaystyle x=\frac{7}{10}y$ what is ratio y:x I come up with 7:10 book says: 10:7 Who is right?

y:x also means $\displaystyle \dfrac{y}{x}$ What is y/x ?
thanks...but still not clear...who is right, me or the book?
What answer did you get with what I told you?
7:10
Nope, you've found the ratio of x:y
Come on! $\displaystyle x = \dfrac{7y}{10} $ $\displaystyle 10x = 7y$ What is $\displaystyle \dfrac{y}{x} = ?$
