Question

An area of 16m^2 can be covered by 1.5 litres of pain. How many litres are needed to cover 20m^2?

Answer 1

Greetings!

Solve for x.

`16:1.5=20:x`

`16/1.5=20/x`
Cross Multiply.

`16*x=20*1.5`
Simplify.

`16x=30`
Divide both sides by 16.

`(16x)/16=(30)/16`
Simplify.

`x=1.875`

1.875 litres of pain would be required to cover an area of 20 meters².

Hope this helps.
