Question

find the average of 4 fractions 11/4 , 16/3 , 25/6 , 17/2










​

Answer 1

Answer:

average= (sum of observations)/(number of observations)

=(11/4+16/3+25/6+17/2)/4

LCM of 4,3,6,2 is 12

So,

11 + 16 +25 +17

4 3 6 2

= {(11 x 3)+(16 x 4)+(25 x 2)+(17 x 6)}/12

= (33+64+50+104)/12

= (251)/12

=20.966667 is approximately equal to 21

average = 21/4

=5.25
