Answer:

5.48

Step-by-step explanation:

First, we convert all the fractions into improper fractions. 1 3/7 is 10/7, 3 5/9 is 32/9, and 1/2 stays the same. then we find a common denominator, which would be the LCM of 7, 9 and 2, which is 126. Finally, we rewrite the fractions with the common denominator of 56, and we get 180/126, 448/9 and 63/126. adding these together we get 691/126, which is approximately 5.48412698, which we can round to 5.48
