Answer:
[tex]\s\frac{143}{18}[/tex]
Step-by-step explanation:
Fractions are easier to add when in improper form.
2 1/2 = 5/2
3 2/3 = 11/3
1 7/9 = 16/9
Now, we need to find a common denominator for these fractions.
18 is a multiple of 2, 3, and 9, so we can use it.
Convert all the fractions to have 18 as denominator:
5/2 = 45/18 (multiply by 9)
11/3 = 66/18 (multiply by 6)
16/9 = 32/18 (multiply by 2)
Now that all the fractions are converted to having the same denominator, we can add them.
[tex]\frac{45 + 66 + 32}{18}[/tex] = [tex]\s\frac{143}{18}[/tex]
