Express as rupees using decimals.
(a) 5 paise
(b) 75 paise
(c) 20 paise
(d) 50 rupees 90 paise
(e) 725 paise

Given:

a) 5 paise

b) 75 paise

c) 20 paise

d) 50 Rs 90 paise

e) 725 paise

To do:

We have to express the given as rupees using decimals.

Solution:

We know that,

$Rs.\ 1=100\ paise$

$1\ paise=Rs.\ \frac{1}{100}$

Therefore,

a) $5\ paise=Rs.\ 5\times\frac{1}{100}$

$=Rs.\ \frac{5}{100}$

$=Rs.\ 0.05$

b) $75\ paise=Rs.\ 75\times\frac{1}{100}$

$=Rs.\ \frac{75}{100}$

$=Rs.\ 0.75$

c) $20\ paise=Rs.\ 20\times\frac{1}{100}$

$=Rs.\ \frac{20}{100}$

$=Rs.\ 0.2$

d) $50\ Rs.\ 90\ paise$

$90\ paise=Rs.\ 90\times\frac{1}{100}$

$=Rs.\ \frac{90}{100}$

$=Rs.\ 0.9$

$50\ Rs.\ 90\ paise=Rs.\ (50+0.9)$

$=Rs.\ 50.9$

e) $725\ paise=Rs.\ 725\times\frac{1}{100}$

$=Rs.\ \frac{725}{100}$

$=Rs.\ 7.25$
