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

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.
Three fourths plus five fourths is equal to eight fourths, or two whole units.
twelve and four twelfths
We convert this to twelfths to give: 10 twelfths + 4 twelfths + 9 twelfths = 23 twelfths or 1 and 11 twelfths.

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