four twelfths since 4/12 ~= 0.333333
8/12, or 2/3
They would have to convert to same denominators to add. So that would be 8 twelfths plus three twelfths. And that is eleven twelfths. 0.916666667
The answer is 19 over 24.
twelve and four twelfths
One fourth is three twelfths. So one twelfth plus three twelfths is four twelfths, which is also one third.

We convert this to twelfths to give: 10 twelfths + 4 twelfths + 9 twelfths = 23 twelfths or 1 and 11 twelfths.

6 and 1/3
Three twelves is 36. Four twelves is 48. 36 - 48 = -12. Three twelfths - fourth twelfths equals minus one twelfth.
It's forty three sixtyiths
10/12 + 9/12 = 19/12 = One and seven-twelfths.
They would have to convert to same denominators to add. So that would be 8 twelfths plus three twelfths. And that is eleven twelfths. 0.916666667
