Answer:

#80#

Explanation:

Percentages can always be written as a direct proportion:

#32# is to #40%# as what number is to #100%#?

#32/40 = x/100" "(larr"number")/(larr"percent")#

#x= (32xx100)/40#

#x = 80#

You can also write an equation and solve it:

Let the unknown number be #x#.

#40%# of that number is equal to #32#

#40/100 xx x = 32#

#x = 32 xx40/100#

#x = 80#
