    ANSWER
    RATIONAL NUMBERS 5 1.2.2 Commutativity (i) Whole numbers Recall the commutativity of different operations for whole numbers by filling the following table. Operation Numbers Remarks Addition 0 + 7 = 7 + 0 = 7 Addition is commutative. 2 + 3 = ... + ... = .... For any two whole numbers a and b, a + b = b + a Subtraction ......... Subtraction is not commutative. Multiplication ......... Multiplication is commutative. Division ......... Division is not commutative. Check whether the commutativity of the operations hold for natural numbers also. (ii) Integers Fill in the following table and check the commutativity of different operations for integers: Operation Numbers Remarks Addition ......... Addition is commutative. Subtraction Is 5 – (–3) = – 3 – 5? Subtraction is not commutative. Multiplication ......... Multiplication is commutative. Division ......... Division is not commutative. (iii) Rational numbers (a) Addition You know how to add two rational numbers. Let us add a few pairs here. 2 5 1 5 2 1 and 3 7 21 7 3 21 − −  + = + =     So, 2 5 5 2 3 7 7 3 − −  + = +    Also, 6 8 5 3 − −  +    = ... and – 8 6 ... 3 5   − + =     Is 6 8 8 6 5 3 3 5 − − − −       + = +             ?

    1/3 - (-5/6) = 1/3 + 5/6 = 1×2/3 + 5×1/6 = 2+5/6 Ans = 7/6. If it is given in mixed fraction form then you have to divide these two numbers.
