Step-by-step explanation:
1. Find common denominators
2. Line up your fractions
3. Add both Numerators straight across
4. Simplify.
We can skip the first step since both fractions have the denominator of 9.
The next step is to line up your fractions from Numerator to Numerator, and from Denominator to Denominator:
23 17
---- + --- =
9 9
Third step, add both of your Numerators straight across:
23 17 40
---- + --- = ----
9 9 9
Lastly, simplifying won't be used in our sum since both the Numerator and Denominator are simplified enough, but we can turn 40/9 into a mixed fraction.
40 / 9 = 4 4/9. ( 4(9/9) + 4/9 ).
Your answers are 40/9 as an improper fraction, or 4 4/9 as a mixed fraction.
