Question

find the ratio of 9 km is to 18 decimeter​

Answer 1

Answer:

5000:1

Step-by-step explanation:

Given,

●1km = 1000m

1m = 100cm

9km = 9×1000×100

= 900000cm

●1decimeter = 10cm

18decimeter = 18 ×10

= 180cm

Ratio = 900000/180

5000:1

Answer 2

Step-by-step explanation:

We convert km into decimeter. So,

1 km = 10,000 dm

9km = 9 ×10,000 dm = 90,000 dm

Finding ratio :

9 km : 18 dm

90,000 dm : 18 dm

90,000 : 18

45,000 : 9

15,000 : 3

5000 : 1

Thus, the ratio is 5000:1.
