Question

anwer my all questions questions 1.(I),2.(I) ,3.(I) ,4.(I),5.(I),6.(I),7.​

Answer 1

4(I) -5/4 -7)3 = -15 -28/12=-43/12

5(i) 5/12-(-7)/12=5+7/12 = 12/12= 1

6(I) 1/6-9/12-22/9= 6-27-88/36 ( take LCM of 6,9,12)

= -121/36

7. a-b = 2/5-7/15= 6-7/15= -1/15

b-a = 7/15-2/5 = 7-6/15 = 1/15

So, (a-b) is not equal to (b-a)
