#Mathricks: Special Percents

Oct 23, 2021

 

 

 

 

 

 

 

 

 

 

 

 

 

“Special percents” are easy to compute because they represent easy-to-calculate amounts.

25% means “a quarter of it

50% means “half of it

100% means “all of it

200% means “all of it, twice

To find 100% of 30 we take “all of it”. All of 30 is 30 and so: 100% of 30 is 30.

To find 200% of 30 we take “all of it, twice”. All of 30 is 30, and double of 30 is 60. So, 200% of 30 is 60.
