Find ratio of:
(a) Rs. 5 to 50 paise
(b) 15 kg to 210 g
(c) 9 m to 27 cm
(d) 30 days to 36 hours
(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,
Required ratio = 20: 1 Ans.
