What does X equal?

Answer 1

`\large\boxed{x=(2)/(5)=0.4}`

Explanation:

`x:6=10:150\\\\(x)/(6)=(10)/(150)\qquad\text{cross multiply}\\\\150x=(6)(10)\\\\150x=60\qquad\text{divide both sides by 150}\\\\(150x)/(150)=(60)/(150)\\\\x=(60\!\!\!\!\diagup)/(150\!\!\!\!\diagup)\\\\x=(6:3)/(15:3)\\\\x=(2)/(5)=0.4`
