UPTET-2019 14 1 FRACTIONS (Part 2) -Piyush Goyal
Relations Between Fractions There are basically 3 types of fractions: 1) Like 2) Unlike 3) Equivalent
Like Fractions .When denominators are same then the fractions are called like fraction .Only like fractions can be added or subtracted. E.g ec 5
Unlike Fractions . When denominators are not same then the fractions are called unlike fraction Unlike fractions cannot be added or subtracted They first needs to be converted to like fraction for addition or subtraction
Equivalent Fractions . Fractions whose numerators and denominators do not have the exact same numerical value however the fraction has the same value -Eg. 1/2=214. . The reason equivalent fractions exist is that the numerator of one fraction and the denominator of that same fraction share a common factor that, when canceled, cause the fraction to have the same value in both the numerator and denominator as another fraction.
