Answer :

(a) We need to find the ratio of Rs 5 to 50 paise

We know that,

1 Rupee = 100 paise

Therefore,

5 Rupees = 500 Paise

Hence,

Ratio = = =

Therefore,

Required ratio = 10: 1 Ans.

(b) We need to find the ratio of 15 kg to 210 g

We know that,

1 kg = 1000 g

Therefore,

15 kg = 15000 g

Hence,

Ratio = = =

Therefore,

Required ratio = 500: 7 Ans.

(c) We need to find the ratio of 9 m to 27 cm

We know that,

1 m = 100 cm

Therefore,

9 m = 900 cm

Hence,

Required ratio = = =

Therefore,

Required ratio = 100: 3 Ans.

(d) We need to find the ratio of 30 days to 36 hours

We know that,

1 day = 24 hours

Therefore,

30 days = 30 × 24

= 720 hours

Hence,

Required ratio = = =

Therefore,
