Question

check the commutative property for - 8/13, 23/27​

Answer 1

Let LHS (left hand side)

a+b=(-8/13 + 23/27) = (-8*27+23*13) / 351= 83/351

Let RHS (right hand side)

b+a=(23/27+(-8)/27) / 351 = 83/351

hence, LHS =RHS

(a+b)(b+a)

which is showing a commutative property.

Answer 2

Step-by-step explanation:

apply the formula a*b= b*a
