Tourist route longest

On the first day, tourists covered 3/14 of the planned route, on the second day 1/3 of the route, and on the third day 8/21 of the route. On which day did they walk the longest part of the route (1,2,3)?

Final Answer:

x =  3

Step-by-step explanation:

$$\begin{gathered} a=\frac{3}{14}\doteq 0.2143 \\ b=\frac{1}{3}\doteq 0.3333 \\ c=\frac{8}{21}\doteq 0.381 \\ a<b<c \\ x=3 \end{gathered}$$
