Step-by-step explanation:

1 km = 1000 m

4/5 km = 800 m

8 3/5 km = 8600 m

8600 m - 800 m = 7800 m

7800 m = 7 4/5 km

Therefore Tejaswini is 7 4/5 km north from her house

Answer:

Tejaswani is 9 2/5 km far from her house .

Step-by-step explanation:

Distance travelled from house to south = 4/5 Km

Distance travelled from south to north = 8 3/5 Km

Total distance travelled = 4/5 km + 8 3/5 km

Solve the mixed fraction

5×8+3 = 40+ 3

43/5

= 4/5 + 43/5

= 4+43/5

= 47/5

Divide 47 by 5

= 9 2/5 Ans
