Question

A scientist has 2 3rd liter of solution. He uses 1 halfof the solution for an experiment. Howmuch solution does the scientist use forthe experiment?

Answer 1

The total amout of solution given is

`(2)/(3)\text{liter}`

From thequestion, 1/2 of the solution is used, then the amount of solution used for the experiment will be

`(2)/(3)*(1)/(2)=(2*1)/(3*2)=(2)/(6)=(1)/(3)\text{liters }`

Hence

The amount of solution the scientist use is 1/3 litres
