Given: 

(i) $7$ paise

(ii) $7$ rupees $7$ paise

(iii) $77$ rupees $77$ paise

(iv) $50$ paise

(v) $235$ paise

To do:

Here we have to express the given amounts as rupees using decimals.

Solution:

We know that,

$Rs.\ 1=100$ paise

This implies,

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

So,

(i) 7 paise

$=Rs.\ \frac{7}{100}$

$=Rs.\ 0.07$

(ii) 7 rupees 7 paise

$=Rs.\ (7+ \frac{7}{100})$

$=Rs.\ (7+0.07)$

$=Rs.\ 7.07$

(iii) 77 rupees 77 paise

$=Rs.\ (77+ \frac{77}{100})$

$=Rs.\ (77+0.77)$

$=Rs.\ 77.77$

(iv) 50 paise

$=Rs.\ \frac{50}{100}$

$=Rs.\ 0.50$

(v) 235 paise

$=Rs.\ \frac{235}{100}$

$=Rs.\ 2.35$
