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 = $\frac{50 \;paise}{Rs \;5}$

= $\frac{50 \;paise}{500 \;paise}$

= $1:10$
