Answer:

19/30

Step-by-step explanation:

let x = 0.4 (bar on 4 ) and y=0.18 (bar on 8)

now, x => 0.4 (bar on 4 ) let this be  equation 1

=>10x = 0.4(bar on 4 )*10=4.4(bar on 4 ) let this be equation 2

equation 2 -1

=>10x - x = 4.4(bar on 4 )-0.4(bar on 4 )

=>9x = 4

=>x = 4/9

now, y = 0.18(bar on 8)​

=>10y = 1.8(bar on 8)​ let this be equation 3

=>100y = 18.8(bar on 8) let this be equation 4

Now, equation 4 - 3

=>100y - 10y = 18.8(bar on 8)​ - 1.8(bar on 8)​

=>90y = 17

=>y = 17/90

now, 0.4 (bar on 4) + 0.18(bar on 8)​

=>x + y

=>4/9+17/90

=>(40+17)​/90

=> 57/90

=> 19/30

hope it helps....
