3/8 of a pizza.
If you divide each pizza into eight parts, each member would receive 1/8 of one pizza. Since there are three pizzas, each member would receive three 1/8 of a pizza, or 3/8.
You can prove this answer by multiplying 3/8 by 8, to get 24/8 simplified to 3.
R/9 = -21
Multiply by 9
r = -189
There would have to be one non club member, and 2 club members who bought the tickets.
Each person should ride the bike for 4 miles, so that every one has to walk 8 miles and ride 4 miles.
If they had 2 bikes, each person will ride for 8 miles, 4 miles on each bike, and then walk 4 miles.
