>>How do you arrive at an answer when a math question is worded as follows?

 1. 6 is ____________% of 20.

 2. 10% of 20 is ____________.<<



I.   Replace any given percent by a decimal by moving the decimal point two

          places left and dropping the "%" symbol.

II.  Replace the word "of" by the multiplication symbol " · ".

III. Replace the word "is" by an equal sign " = ".

IV.  Replace the blank _____ by " x "

V.   Solve the equation.

VI.  If the blank has a "%" sign after it, change the answer to a 

           percent by moving the decimal point two places right.

                  

>>1. 6 is ____________% of 20.

    6   =       x       ·  20

             6 = x·20

             6 = 20x

    Divide both sides by 20

           6/20 = 20x/20

             .3 = x

Since there was a "%" after the blank, we change .3 to 30%. 

>>2. 10% of 20 is ____________.<<

    0.10  · 20  = x

      (.10)(20) = x

              2 = x

 The way I learned to solve this problem was to put



is    %      6    %

__ = __     __ = ___  =30%

                

of   100    20   100



I put the 6 in the is spot, leave the percent blank cause you got to solve it, 20 in the of spot. Multiply 6 X 100 then divide by 20 and your answer is 30%.





is   %            10%

__ =__     ____ =____  =2



of  100    20     100



I leave the is blank so you can solve it, put 20 in the of spot,10% in the percent spot. Then you multiply 10% by 20 then divide by 100 then you get the answer 2. 



Let me know if you understand it that way. That is how I was taught to do the problem.

 When solving word problems, it is preferably easier to change unknown values to any letter, but I like "x" best!







1. 6 is ____% of 20.



Solution

Question becomes;

6 is x% of 20.



Next, we represent "is" with "=", "%" with "/100" and "of" with "X" i.e;





Next, we re-arrange properly, i.e;










Cross multiply:





Divide both sides by 20:






therefore, x = 30!

Recall the question;

6 = x% of 20



From solution, x = 30 so,

6 = 30% of 20





2. 10% of 20 is _______.



Solution

As before, replace dash with x;

10% of 20 is x.



Now represent values as before;
















Recall Question;

10% of 20 is x



From solution, x=2 so,

10% of 20 is 2.





I only made it elaborate so it would be very explanatory. Hope it helped.
