Question

2.Name the property under addition used in each of the following :

(iii) 8 + 7/10 = 7/10 +8

Answer 1

Commutative Property under

Addition :

******************************************

If a , b are Rational Numbers ,

a + b = b + a

******************************************

Here ,

a = 8/1 , b = 7/10 ,

8/1 + 7/10 = 7/10 + 8/1

Answer 2

Answer : Commutative Property

Explanation :

It's Under the Commutative Property

In commutative property, we can replace the number place but the answer always should be same.

For example:

In Addition :

A + B + C = C + B + A  

A + B + C = B + C + A  

A + B + C = C + A + B

In Numbers : 2 + 3 + 4 = 4 + 3 + 2 = 3 + 2 + 4

In Multiplication :

A * B * C = C * B * A  

A * B * C = B * C * A  

A * B * C = C * A * B

In Numbers : 2 * 3 * 4 = 4 * 3 * 2 = 3 * 2 * 4
