how do you solve percentages of decimals like the 36% of 4.58?

Question

anonymous · Answer

a percentage of another number is the same as multiplying that percentage by the number.

Like 30% of 10 is the same as 30% * 10... which is like 0.30 * 10 = 3

It is the same idea when finding a percentage of a decimal number... just multiply the percentage times the other number.

a percentage is another way of writing a fraction of decimal... 

you can change your percentage to a fraction 36/100 or a decimal 0.36 and just multiply your quantity

0.36 x 4.58 =   or 36/100 x 4.58 

an alternate method is to find 10%

10% of 4.58 = 0.458      so 30% = 3 x 0.458

                                          5% = 0.458/2                 

                                           1% = 0.0458 
                                           -------------
add them for                      36% =
