Question

Is subraction associative is rational numbers?Explain with an example.​

Answer 1

Answer:

No substraction don't follow associative property ..

Step-by-step explanation:

formulae=a-(b-c)=(a-b)-c

a=1/5 b=2/5 c=3/5

1/5-(2/5-3/5)=2/5

(1/5-2/5)-3/5= -4/5

so,substraction is not associative with rational numbers

                                   

Ex..(2 - 4) -3 = -2 -3

= -5

while .2 - ( 4 -3) = 2 - 1

= 1
