First convert each number in rational
0.2 bar = 2/9
0.3 bar = 3/9
0.4 bar = 4/9
0.9 bar = 1
0.39 bar = 39 /99
Required sum is in the attachment......
0.2 bar = 2/9
0.3 bar = 3/9
0.4 bar = 4/9
0.9 bar = 1
0.39 bar = 39 /99
Required sum is in the attachment......

Given 0.2(bar) + 0.3(bar) + 0.4(bar) + 0.9(bar) + 0.39(bar).
0.2 + 0.3 + 0.4 + 0.9 + 0.39 = 2.19.
Let x = 2.19 ------------ (1)
Multiply both sides by 10, we get
10x = 21.9 ---------- (2)
On solving (2) & (1), we get
10x - x = 19.7
9x = 19.7
x = 19.7/9
x = 2.18.
I am not sure about it. If its wrong, report it.
