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.
To add three twelfths to three fourths, we first need to find a common denominator. The least common multiple of 12 and 4 is 12. Converting three fourths to nine twelfths, we can now add three twelfths to nine twelfths to get twelve twelfths, which simplifies to one whole. Therefore, three twelfths plus three fourths equals one whole.

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
