Thank you for the opportunity to help you with your question!

First, lets convert these mixed fractions into simple fractions: 1 and 7/9 = ((9*1)+7)/9 = 16/9 and 3 and 1/5 = ((5*3)+1)/5 = 16/5. Now, 16/9 + 16/5 = ((16*5)+(16*9))/45 (Taking the lowest Common Multiple or L.C.M.) = 45 so multiplying and dividing 16/9 by 5 to make up 45, (16*5)/(9*5) = 80/45 multiplying and dividing 16/5 by 9 to make up 45, (16*9)/(5*9) = 144/45. Therefor, 80/45 + 144/45 = (80+144)/45 = 224/45 = 4.977777778 = 4.98.

Please let me know if you need any clarification. I'm always happy to answer your questions.
