##### I need help solving for an unknown when it's in the denominator's place

 Mathematics Tutor: None Selected Time limit: 1 Day

1/3 = 25/y   When I solve this I get y = 1/75, but that's not right and I don't understand why.

$\frac{1}{3}=\frac{25}{y}\\ \\ Cross\hspace{5}multiply\\ \\ 1*y=25*3\\ \\ y=75$
