Basics in fractions.

Basic mathematics.these are a basic maths question.it is also used in basic maths for competitive exams. These basic maths formulas are compulsory applicable in solving Algebra problems.


Addition and subtraction of two fractions:

1) 2/3 + 4/5  =2*5 + 4*3 / 3*5
                     =10/15+ 12/15
                     =10 + 12/15
                     =24/15( divisible by 3 table )
                     =8/5
     
      In the above example first, we should make the denominators with the same number.
So that cross multiple the numbers.

2) 2/3 - 4/5  =2*5 - 4*3 / 3*5
                     =10/15 - 12/15
                     =10 - 12/15
                     = - 24/15( divisible by 3 table ) n                                       get bigger number sign.
                     = - 8/5

Multiplication and Division of two numbers:

 1) 2/3 * 4/5  =2 * 4 / 3 * 5
                     = 8 / 15
                   
         In the above example, numerator numbers will multiply and denominator number will multiply.
         
  2)   2/3   /   4/5  =2/3   /  4/5
                             =2/3 *  5/4(in this step by multiply sign will come and get the reciprocal number of 4/5.

                             =2 * 10/ 3 * 4 ( in this same as multiply)
                             =20/12

                             =10/6 ( divisible by 2 tables in one time.)
                             =5/3 ( divisible by again 2 tables).


       So, students don't make silly mistakes.
