Question

The average of the middle two rational numbers when 4/3,-4/15, 7/2,-6/10 are arranged in ascending order​

Answer 1

Here is the solution

Answer 2

Step-by-step explanation:

take the lcm of all the denominators

LCM(3,15,2,10) =30

Now change all the fractions to get 30 as denominators.....

4/3*10/10=40/30

-4/15*2/2=-8/30

7/2*15/15=105/30

-6/10*3/3=-18/30

since all denominators are same just arrange the numerators

-18<-8<40<105

so middle 2 terms are

-8/30 & 40/30

average=( -8/30+40/30)/2

=32/(2*30)

=8/15
