HI Adyut, THANKS FOR THE WORK YOU SENT ME WHEN I WAS ABSENT . I AM FACING SOME PROBLEM IN RATIONAL NUMBERS .CAN YOU EXPLAIN ME ?
WHY NOT? TELL ME THE TOPICS THAT YOU ARE FACING IN RATIONAL NUMBERS.

OH! THAT'S VERY SIMPLE . IN ADDITION , YOU JUST NEED TO MAKE THE DENOMINATOR SAME BY FINDING LCM .ONCE YOU MAKE THE DENOMINTOR SAME ,ADD UP THE NUMERATORS OF THAT 2 OPPOSITE RATIONAL NUMBERS . FOR EXAMPLE :2/10 + 3/5 = 2/10+6/10 =8/10 =4/5IN MUPLTICATION ,YOU NEED TO MULTIPLY THE NUMERATOR DENOMINTOR WITH THE NUMERATOR DENOMINATOR OF THE OTHER RATIONAL NUMBER AND IF CROSS MULTIPLICATION IS POSSIBLE ,YOU CAN DO IT TO .FOR EXAMPLE :3/5*4/2 =3*4/5*2 =12/10 = 6/5
ADDITION MULTIPLICATION OF 2 OPPOSITE RATIONAL NUMBERS.
DO YOU HAVE ANY OTHER PROBLEM IN RATIONAL NUMBERS ?

Commutative property of addition of rational numbers is very simple .The commutative property of rational numbers includes addition, subtraction, multiplication, and division. For two Rational Numbers, say 'a' and 'b,' the commutative law of addition states that a + b = b + a. EXAMPLE:3+2=2+35=5Closure Property is simple too. The closure property of rational numbers states that when any two rational numbers are added, subtracted, or multiplied, the result of all three cases will also be a rational number .
Commutative property of addition of rational numbers closure property of rational numbers. I have a little bit confusion on them .
