Question

For Each Of The Following , Check That a ÷ b ≠ b ÷ a:

(a). a = 2/5 and b = 9/11
(b). a = -5/7 and b = 12/15​

Answer 1

Answer:

(a) a = 2/5 and b =9/11

a÷b = 2/5÷9/11

= 2/5×11/9=22/45

b÷a = 9/11÷2/5

= 9/11×5/2=45/22

SO a÷b do not equal to b÷a

(b) a= -5/7 and b=12/15

a÷b = -5/7÷12/15

= -5/7×15/12= -75/84 = -25/26

b÷a = 12/15÷ (-5/7)

= 12/15 × (7/-5)

=84/-75= 26/-25

SO a÷b do not equal to b÷a ANSWER
