Answer:

72

Step-by-step explanation:

Lets say total number of Outdoor club member = x

Members going for hiking = \frac{x}{2}

Members going for bike riding = \frac{x}{4}

Members going for rock climbing = \frac{x}{8}

Member going for walking their dogs = 9

Thus,

x=\frac{x}{2}+\frac{x}{4}+\frac{x}{8}+9

x-\frac{x}{2}-\frac{x}{4}-\frac{x}{8} = 9

\frac{8x-4x-2x-x}{8}=9

\frac{x}{8}=9

x=72

72 Outdoor Club members are doing an activity on Saturday.
