Answer 1

Answer:

i) LCM of the denominators(5,2,15,10)=30

Then,

2/5=2*6/5*6=12/30

-1/2= -1*15/2*15= -15/30

-8/15= -8*2/15*2= -16/30

3/10= 3*3/10*3= 9/30

We see,

12/30>9/30>-15/30>-16/30

2/5>3/10>-1/2>-8/15

ii) LCM of the denominators(10,15,30,5)=30

Then,

-7/10= -7*3/10*3= -21/30

-8/15= -8*2/15*2= -16/30

19/30= 19*1/30*1= 19/30

2/5= 2*6/5*6= 12/30

We see,

19/30>12/30>-16/30>-21/30

19/30>2/5>-8/15>-7/10
