A. 3
B. 8
C. 9
D. 28
E. 29
We can solve this question using
equivalent ratiosWould use the ratio:
liters of water/
number of monkeys sustainedWe'll let
x = number of monkeys 16 liters of water can sustain
So we can write:
9/
5 =
16/
xCross multiply to get: 9x = (5)(16)
Simplify to get: 9x = 80
Divide both sides by 9 to get x = 80/9 = 8.something
This tells us that 16 liters of water CANNOT sustain 9 monkeys
So the
maximum number of monkeys that CAN be sustained by 16 liters of water is 8
Answer: B
