If two ratios have the same value when simplified, then they are equivalent ratios. In the conversion of money, we will learn to convert the amount from paise to rupees. Conversion from paise to rupees is based on the basic fact that Re. 1 = 100 paisa.

Here, in this question, we need to first convert either of the units to another unit and then find the ratio of the two quantities.

For finding the ratio, we need to convert both the terms in the same unit, as the ratio is always unit less for the same measuring units.

Since, \[Rs.{\text{ }}1 = 100{\text{ }}paisa\] so, by following the unitary method we get,

$

Rs{\text{ }}5 = 5 \times 100{\text{ paise}} \\

= 500{\text{ paise}} \\

$

Now, the ratio is given as,

$

{\text{Ratio = }}\dfrac{{{\text{50 paise}}}}{{{\text{500 paise}}}} \\

{\text{ = }}\dfrac{{\text{1}}}{{{\text{10}}}} \\

$

Hence, the ratio of 50 paise to Rs 5 is $\dfrac{1}{{10}}$
