1 7/12 (one and seven-twelfths)
3 3/8
One third is four-twelfths, one quarter is three-twelfths, add one-twelfth. So the total is eight-twelfths (two thirds).
To add the fractions five ninths and negative three eighths, you need to find a common denominator. The least common multiple of nine and eight is 72. Convert both fractions to have a denominator of 72 and then add the numerators. The result is -17/72.
A common denominator is 32.
Add five eighths
Four eighths
The denominators are different, so find the equivalent fractions using the LCD , then add the fractions with the denominators.
1 7/12 (one and seven-twelfths)
That would be 5 eighths. Since 1/2 is equal to 4 eighths, you simply add 1 and 4 together to make five. (The eighths part stays the same)
five twelfths 7/12 + 5/12 = (7 + 5)/12 = 12/12 = 1/1 = 1
Two and three-eighths plus one and seven-eighths equals four and two-eighths, which can be to four and one-fourth. Here's how to find the answer. First, you add the two whole numbers together, giving you three. Next, since you are adding two fractions with the same denominator, you add the numerators together, which gives you ten eighths. You then convert that to one and two eighths and add the one to three which is four. Finally, you divide both the numerator and the denominator by two. The final answer is four and one-fourth.
3 3/8
One third is four-twelfths, one quarter is three-twelfths, add one-twelfth. So the total is eight-twelfths (two thirds).
To add the fractions five ninths and negative three eighths, you need to find a common denominator. The least common multiple of nine and eight is 72. Convert both fractions to have a denominator of 72 and then add the numerators. The result is -17/72.
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
