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....
