Question

If p= -3/2 q=4/5 and r= -7/12 then verify that( p÷q)÷r (not equal to) p÷(q÷r)

Answer 1

Hi ...dear...
here is your answer!!!....
... Given,.
p=-3/2,
q=4/5 ,
r=-7/2....
...then,
p÷q= -3/2 ÷ 4/5
.......= (3*5)/(2*4)....
= -15/8
....again,.
(p÷q)÷r= -15/8 ÷ (-7/2).........
...............=(15*2)/(8*7)
...... = 30/56
(p÷q)÷r =-15/28>>>>>>>>>>(1)
................................
q÷r= 4/5 ÷ (-7/2).
= ......-(4*2)/(5*7).
= - 8/35
....
p÷(q÷r)= -3/2÷ (-8/35)..
........= 3*35 / 2*8
= 105/16....

p÷(q÷r)= 105/16>>>>>>>>>>>2)...
form one and two...
.

(P÷q)÷r≠p÷(q÷r)>>>>
hence porved..!!
hope it helped you!!
