A Decimal fraction is a fraction (as 25/100) in which the denominator is a power of 10.
Recall that a percent shows a part out of 100 (a percent is a decimal fraction with a denominator of 100). A percent means how many for each 100.
Thus, if we know any two of these three quantities, it is easy to calculate the third one.
There are three basic types of percent problems:
Type 1: Finding the Percent (%) or Rate
Type 2: Finding the Part
Type 3: Finding the Base or Whole
Example: From a group of 30 students 50% are taking math. The number of students taking Math is 30 x 50/100 = 15 (half of 30)
