1/2 = 6/122/3 = 8/123/4 = 9/12 (generally called quarters not fourths)(6+8+9)/1223/12one and eleven twelfths, or twenty-three 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

5 0ver 6 I always hated these questions in Algebra. But they're pretty simple, if you can make the two parts more equal. Since Twelfths and Fourths are different, you have to get them to be the same. It's easier to convert 4ths to 12ths, since Four Goes Into 12 Three times - so ONE FOURTH is the same as THREE TWELFTHS, right? That's the tricky part, right there - being able to see the relationship between FOURTHs and TWELFTHs. So 7/12ths plus 3/12ths is 10/12ths, right? Which is the same as 5/6ths. The first answerer didn't tell you HOW he got the answer, so you were no better off in case it came up again.
twelve and four twelfths
We convert this to twelfths to give: 10 twelfths + 4 twelfths + 9 twelfths = 23 twelfths or 1 and 11 twelfths.
2/4 + 3/12 = 2/4 + 1/4 = 3/4

Seventeen eighths or two and an eighth.
We convert the fractions to twelfths: 1 + 8 twelfths + 9 twelfths. 1 + 17 twelfths 2 and 5 twelfths.
First we convert to the same type, which is twenty-fourths: 6 twenty-fourths + 9 twenty-fourths + 10 twenty-fourths = 25 twenty-fourths or 1 and 1 twenty-fourth.
1/2 = 6/122/3 = 8/123/4 = 9/12 (generally called quarters not fourths)(6+8+9)/1223/12one and eleven twelfths, or twenty-three twelfths

Seven-twelfths
Three fourths plus five fourths is equal to eight fourths, or two whole units.
