Question

if p =5 by 6,q=-7by 6 and b=13 by16,then verify that (p+q)+r=p+(q+r)​

Answer 1

Answer:

Here is your question's answer

But instead of b there is r in the question

Answer 2

Answer:

23/48

Step-by-step explanation:

p= 5/6,q= -7/6. r= 13/16

(p+q)+r

= (5/6+(-7/6)+13/16)

= 5/6-7/6+13/16

= -2/6+13/16

= -16+39/48

= 23/48

p+(q+r)

= 5/6+(-7/6+13/16)

= 5/6-17/16

= 40-17/ 16

= 23/48
