PERCENT

Mathematics is made up of 50% formulas, 50% proofs and 50% imagination.

The word „percent“ is based on the term „per cent“ and in Latin means „out of a hundred“.

Percentages can always be rewritten into a fraction (therefore their symbol resembles a fraction line).

 

Percent to fraction conversion:

  • Make the percentage the numerator of the fraction
  • „Per cent“ means out of every 100, so 100 is used as the denominator
  • Simplify if possible
  • Divide the numerator
  • Multiply by 100
  • Add a percent symbol

Percent as rule of proportion – this is a direct proportion

 

EXAMPLE

What is 8 percent of 50? X is 8 percent of 50.

  • Multiple by cross: (x) (100) = 50 (8)
  • 100x = 400
  • divide both sides by 100
  • x = 4

Employees who will not work on 100% will have their salary reduced by 50% and then increased by 50%!

Employees give work 100% = 10% on Monday, 21% on Tuesday, 41% on Wednesday, 20% on Thursday and 8% on Friday.

YOU KNOW THAT:

A 5% climb does not mean a slope. The data indicates that the traveler will ascend 5 meters in 100 meters.

There is a difference between „100%“ (with a space) and „100%“ (without a space). A version with a space means „one hundred percent“, while a version without a space means „hundred-percent“.

Percentage can be swapped actors? 8% of 50 is the same as 50% of eight.
