Vidya

Vidya and Peter went for a picnic. Their mother gave them a 5-liter water bottle. Vidya consumed 2/5 of the water, and Peter consumed the remaining water.
How much water did Vidya drink?
How much water did Peter drink?

Final Answer:

a =  2 l
b =  3 l

Step-by-step explanation:

$$\begin{gathered} V=5\text{l} \\ a=\frac{2}{5}\cdot V=\frac{2}{5}\cdot 5=\frac{2\cdot 5}{5}=\frac{10}{5}=2\text{l} \end{gathered}$$

$b=V-a=5-2=3\text{l}$
