Thermal distillation involves heating of the salty water. Boiling water turns it into vapour, leaving the salt behind.The vapours are collected and condensed back into the water by cooling it down. 

Given: $X:Y: : 5:2$ To do:  Find $9y:8x + 2y$ =?Solution: If $x:y =5 :2$, then (8x+9y):(8x+2y) =  ? Let $x = 5k$ and $y = 2k$; $\frac{x}{y} = \frac{5k}{2k} = \frac{5}{2}$ $(8x+9y):(8x+2y)$=$\frac{8x+9y}{8x+2y}$ =$ \frac{8 \times 5k+ 9 \times 2k}{8 \times 5k + 2 \times 2k}$ = $\frac{40k + 18 ...
