<human>:  In a field of 500 clovers, 20% have four leaves and one quarter of these are purple clovers. Assuming these proportions are exactly correct, how many clovers in the field are both purple and four-leaved?
<bot>: How many four leaf clovers are there? ** There are 500/5= <<500/5=100>>100 four leaf clovers
How many purple four leaf clovers are there? ** There are 100/4= <<100/4=25>>25 purple four leaf clovers
