(a) Rs 5 to 50 paise
First, convert the given quantities into the same units,

So,  Rs 5 = 5 \times 100 = 500 paise
Now, Ratio = \frac{500}{50} = 10:1

(b) 15 kg to 210 g
Converting the given quantities into the same unit.
So, 15 kg = 15 \times 1000 = 15,000 g
Therefore, Required ratio 
\\=\frac{15000}{210}=500:7

(c) 9 m to 27 cm
First, convert meter into centimetre
So,  9m = 9 \times 100 = 900 cm
Therefore, the required ratio 
 \frac{900}{27}=100:3

 (d) 30 days to 36 hours
 Converting the given quantities into the same unit. 
So, 30 days = 30 \times 24hr = 720 hrs
Therefore, the ratio
\frac{720}{36} = 20:1
