Mathnasium #MathTricks: Special Percents (Basic)

By Mathnasium | October 22, 2021

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

0% means “none of it

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.
