Question

Find the ratio of the following: 

1. Speed of a cycle \(15\) km per hour to the speed of scooter \(30\) km per hour. 
2. \(5\) m to \(10\) km 
3. \(50\) paise to Rs \(5\)

Answer 1

(a) Ratio of the speed of cycle to the speed of scooter = \(\frac{15}{30}\) 
= \(1:2\)

---

(b) Since \(1\) km = \(1000\) \(m\),

Required ratio = \(\frac{5\; km}{10\;km}\) 

= \(\frac{5\;m}{10}× 1000\; m\)

 = \(1:2000\)

---

(c) Since Rs \(1 = 100\) \(\text{paise}\),

Required ratio = \(\frac{50 \;paise}{Rs \;5}\) 

= \(\frac{50 \;paise}{500 \;paise}\) 

= \(1:10\)
