Answer 1

Question :-

Identify the property used in the following

$\sf {\frac{2}{3} +(\frac{4}{5} +(-\frac{6}{7})=(\frac{2}{3} +\frac{4}{5} )+(-\frac{6}{7})$

AnswEr :-

⇒ It uses Associative Property.

What is Associative Property ?

This property states that we can add numbers regardless of the way they are grouped, i.e. used parenthesis.

An Example is shown below :-

a + (b + c) = (a + b) + c = b + (a + c)

To make it more clear,

a = 1

b = 2

c = 3

Now,

1 + (2 + 3) = (1 + 2) + 3 = 2 + (1 + 3)

= 1 + 5 = 3 + 3 = 2 + 4

= 6 = 6 = 6

Answer 2

It is associative property
