Meaning of percent • During yours exams , you are always busy comparing your marks with other children’s marks or you are even interested to in which subject your performance is better. • Suppose , Rajesh got 18 marks out of 25 and Gopal got 14 out of 20 in Maths, who did better? • We express the marks as fraction of 1. • Thus , we get 18 25 marks of Rajesh and 14 20 of Gopal. • We can , now compare 18 25 and 14 20 18 25 > 14 20 since 18×20>14×25 We thus, find that Rajesh’s performance is better. 3
Lets answer some questions 4  A percent is a ratio whose second term is 100. The word percent is derived from latin word ‘per centum’ , which means per hundred. We use symbol ‘ %’ for percent. Thus,  72 percent= 72% = 72 100 . Percent means parts per hundred.  To change Decimal into percents  Example- (i) 0.125 = (0.125 × 100) = 12.5%  Rule – To covert a decimal into percent we move the decimal point two places to the right and insert % symbol.
