48

Explanation:

#100% of 75 =75#

#so 10% 75= 7.5#
#=> 60% of 75= 6 *7.5 = 45#

#and 2% of 75 = 10/5% of 75 = 7.5/5 =1.5 #
#so 4% = 1.5* 2 =3.0#

therefore #64% of 75 = 60% of 75 +4 % of 75 = 45+3 =48#

#color(blue)(64%" of " 75= 48)#

A full explanation is given (in detail) about what is happening and what things mean.

Explanation:

When percentage is presented in the format of 64% it is a shorthand notation for #64/100#. So basically, it is a fraction.

Lets split up the wording percent:

Per means: 'for each'

cent means: one hundred. Think of century or centimetre

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So the question: "What is 64% of " is saying:

#64/100 " of " 75#

That is: split up 75 into 100 equal sized parts and put together 64 of them.

By the way, although not normally done it is perfectly correct to write #75" as "75/1#

I am going to do this to demonstrate without room for doubt what is happening:

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#color(blue)("Solving your question")#

#64/100 xx 75/1" "=" " (64xx75)/(100xx1)" " =" "48 #
