Answer:

wrong as his calculation was incorrect at initial level itself when he found the result of the division

Step-by-step explanation:

Andre said

3 ÷ $\frac{2}{3}$

$=3 \times \frac{3}{2}$

$=\frac{3 \times 3}{2}$

$=\frac{9}{2}$

but andre calculated it as

$=4\tfrac{1}{3}$

$=\frac{4 \times 3 + 1}{3}$

$=\frac{13}{3}$

Hence his calculation was incorrect at initial level itself

Answer:

$1\frac{1}{3}$

Step-by-step explanation:

Total Volume of Water = $5\frac{4}{6}$

Volume drunk by James = $1\frac{1}{3}$

Volume drunk by Simon = $\frac{2}{3}$

Volume drunk by Matthew = $1\frac{1}{2}$

Volume drunk by Gilbert = $\frac{5}{6}$

Total Volume Drunk (i.e. The Sum) = $1\frac{1}{3} + \frac{2}{3} + 1\frac{1}{2} +\frac{5}{6}=\frac{13}{3}$

Volume of water Left = Total Volume of Water-Total Volume Drunk

= $5\frac{4}{6}-\frac{13}{3} =\frac{4}{3}=1\frac{1}{3}$
