Answer:

1)She ran 4 23/60 km in 2 days

2)3/20

3)3/4

Step-by-step explanation:

Thrus - (37/20)km

Fri - (38/15)km

Total = (37/20)+(38/15)

= [(37×3)/(20×3)]+ [(38×4)

/(15×4)] (make denorminator same)

= (111/60)+(152/60)

= 263/60

= 4 23/60

(3/10)×(2/4)

= (3/10)×(1/2)

= (3×1)/(10×2)

= 3/20

(1/2)÷(2/3)

= (1/2)×(3/2)

= (1×3)/(2×2)

= 3/4
