Since we need 4/3 liters of water to water 2/5 of the plants in the house, then we need


(4)/(3)/(2)/(5)\text{.}

of water to water all the plants.

Recall that:


((a)/(b))/((c)/(d))=(ad)/(bc)\text{.}

Therefore:


((4)/(3))/((2)/(5))=(4*5)/(3*2)\text{.}

Simplifying the above result, we get:


(20)/(6)=(10)/(3)\text{.}

Answer:


(10)/(3)\text{ liters.}
