[tex] = 3 \frac{2}{7} + 4 \frac{7}{9} \\ \\ = \frac{7 \times 3 + 2}{7} + \frac{9 \times 4 +7 }{9} \\ \\ = \frac{23}{7} + \frac{43}{9} \\ \\ = \frac{207 + 301}{63} \\ \\ = \frac{508}{63} [/tex]

Answer:
508/63
Step-by-step explanation:
First, convert the mixed fraction to improper fraction
3 2/7 = 23/7
4 7/9 = 43/9
Then, convert them to like fractions
LCM = 63
23*9 / 7*9 = 207/63
43*7 / 9*7 = 301/63
Now, Add them
= 207/63 + 301/63
= 207+301 / 63
= 508/63
