for every 12 monkeys that a zoo keeps it must hire 3 zookeepers if a zoo is rehabilitating 228 monkeys does the zoo need

To find out how many zookeepers the zoo needs for 228 monkeys, we can set up a proportion based on the ratio given: for every 12 monkeys, the zoo must hire 3 zookeepers.

First, we can determine how many groups of 12 monkeys are in 228:

\[
\text{Number of groups} = \frac{228}{12} = 19
\]

Next, since each group of 12 monkeys requires 3 zookeepers, we can calculate the total number of zookeepers needed:

\[
\text{Total zookeepers} = 19 \times 3 = 57
\]

Therefore, the zoo needs **57 zookeepers** to take care of 228 monkeys.
