Question

Find the ratio of :
$\left(a\right)Rs5$ to $50$ paise
$\left(b\right)15kg$ to $210g$
$\left(c\right)9m$ to $27cm$
$\left(d\right)30$ days to $36$ hours.

Answer 1

a) $Rs.5$ to $50$ paise

$Rs.5=5\times 100$ paise

$=500$ paise

Ratio $=\frac{500}{50}=\frac{10}{1}$

$=10:1$

b) $15kg$ to $210$ gm

$15kg=15\times 1000$ gm

$=15000gm$

Ratio $=\frac{15000}{210}=\frac{500}{7}$

$=500:7$

c) $9m$ to $27cm$

$9m=9\times 100cm$

$=900cm$

Ratio $=\frac{900}{27}=\frac{100}{3}$

$=100:3$

d) $30$ days to $36$ hours

$\Rightarrow 30$ days $=30\times 24$ hrs

$=720hrs$

Ratio $=\frac{720}{36}=\frac{20}{1}$

$=20:1$
