Answer :

1/5, 0.4, then 60%.  Because if you multiply 0.4 by 100, you get 40%, and then you do the same thing for 1/5.


1/5 , 0.4, 60%        1/5 converts by dividing 5 into the 1 =0.2 or 20%   the 0.4 = 40% move the decimal point to the right to convert from decimal to the percentage then line

up from smallest number to largest   1/5, 0.4,  60%
