Answer:


(29)/(35) or ~0.83km

Explanation:


(3)/(7) + (2)/(5) = (29)/(35)

make the denominators the same in order to find total in addition

3 • 5 = 15

7 • 5 = 35

2 • 7 = 14

5 • 7 = 35


(15)/(35) + (14)/(35) = (29)/(35) or ~0.83km

Answer:

0.83 Km

Explanation:

First day she walked 3/7 Km

Second day she walked 2/5 Km

Simple addition problem where they ask for the sum of how may Km she walked in those two days therefore:

3/7 + 2/5 = 29/35 Km

or about 0.83 Km
