Completely forgot how to solve these:

Find the missing values: \(7:4:10=x:y:30\)

 

Thanks in advance!

Never mind, I figured it out.

 

1. \(\frac{\frac{7}{4}}{10}=\frac{\frac{x}{y}}{30}\)

 

2. \(\frac{3}{3}*\frac{7}{4}=\frac{x}{4}\)

 

3. \(\frac{21}{12}=\frac{x}{y}\)

 

Finally: \(x=21; y=12\)
