Question

verify the property communicative of multiplication -5/7​

Answer 1

$\huge\bold\green{Solution}$

• For multiplication, the commutative property formula is expressed as

$\huge\boxed{\dag\sf\red{ (A × B) = (B × A).}\dag}$

$\huge\boxed{\dag\sf\red{(A × B)}\dag}$

$Let A= \frac{ - 5}{7}$

$but \: B=\frac{ - 5}{7}$

$\frac{ - 5}{7} \times\frac{ - 5}{7} = \frac{25}{49} (1)$

Now ,

$\huge\boxed{\dag\sf\red{(B×A)}\dag}$

$Let \: B=\frac{ - 5}{7}$

$but \: A= \frac{ - 5}{7}$

$\frac{ - 5}{7} \times\frac{ - 5}{7} = \frac{25}{49} (2)$

• Hence it is verified that,multiplication is communicative for rational number

$\huge\boxed{\dag\sf\red{Thanks}\dag}$
