150 deer were tagged

Explanation:

We are told that 20% of 60% are males older than 4 1/2
There are 18 of these males.

If the total number of deer is x, we can write an equation to show the process:

20/100 xx60/100 xx x = 18

Now solve for x by isolating it.

cancel20/cancel100 color(red)(xxcancel100/cancel20) xxcancel60/cancel100 color(blue)(xxcancel100/cancel60)xx x = 18 color(red)(xx100/20) color(blue)(xx100/60)

x = cancel18^6 xxcancel100^5/cancel20xxcancel100^5/cancel60^cancel3

x = 6 xx5xx5

x = 150
