thank u smmm do u mind explaining to me i dont rlly get it
9.45
Start from 5,
what number - c = 5
It should be 10 - 5 = 5
Therefore C = 5
Then 4
When C = 5 after gave 1 to 0, left 4
4 - B = 4
So, B = 0
Lastly, 9
AB - A = 9 as we knew that B=0
A0 - A = 9
It must be 10 - 1 = 9
Hence, A = 1
So the three digits 105
Check
10.5 - 1.05 = 9.45 correct
