#21.6%# and #27/125#

Explanation:

PERCENT: Multiply by #100%#.

#0.216*100%=21.6%#

FRACTION: Count the number of numbers after the decimal and write that number of zeros after #1#. Divide only the numbers after the decimal by this number.

#0.216-> 3# numbers after decimal

#1# _ _ _ #->1000#

#216/1000#

Simplify as needed!
#cancel(216)/cancel(1000)=27/125#
