Answer:

The percent of change of number of students in the math club # = 15.63% # (decrease)

Explanation:

Finding percentage change involves finding the difference between initial value and ending value.

Initial value #=32#

Final value #=32 - color(blue)(5) = 27# (#5# students are transferred to the chemistry club.)

So the change in number #= 32 - 27 = color(green)(5#

Now the percentage change is calculated as follows:

#=# (change in value) #/# (initial value) #xx 100#

# = (5) / (32) xx 100#

# = (500) / (32) #

# = 15.63% # (rounding off to nearest #100#)

The percent of change of number of students in the math club # = 15.63% # (decrease)
