Find the ratio of the following:
(a) 30 minutes to 1.5 hours
(b) 55 paise to Rs. 1
Given :
The given terms are (a) 30 minutes to 1.5 hours and (b) 55 paise to Rs. 1.
To do :
We have to find the ratio of the given terms.
Solution :
(a) 30 minutes to 1.5 hours.
We know that,
$1\ hour = 60\ minutes$
$1.5\ hours = 1.5\times60\ minutes=90\ minutes$
This implies,
$30\ minutes : 1.5\ hours = 30\ minutes : 90\ minutes = 1:3$.
Therefore, the ratio of 30 minutes to 1.5 hours is 1:3.
(b) 55 paise to Rs. 1.
We know that,
$Rs. 1 = 100\ paise$
This implies,
$55\ paise : Rs. 1 = 55\ paise : 100\ paise = 11:20$.
Therefore, the ratio of 55 paise to Rs. 1 is 11:20.
