Verified answer

Answer:

Step-by-step explanation:

0.2(bar on 2) = 0.222

let x = 0.222     ....(eq-1)  

multiply by 10 on both sides

10x=2.22          ....(eq-2)

now  

(eq2) - (eq1)

9x=2

x=2/9

similarly

for 0.3(bar on 3)

x=3/9

for 0.4(bar on 4)

x=4/9

for 0.5(bar on 5)

x=5/9

now add all x

sum = 2/9+3/9+4/9+5/9

sum = 14/9 (Answer)
