Answer:

#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#
