Question

Try These a
1. Saurabh takes 15 minutes to reach

takes one hour to reach school
from his house. Find the ratio of
the time taken by Saurabh to the
time taken by Sachin.
2. Cost of a toffee is 50 paise and
cost of a chocolate is 10. Find the
ratio of the cost of a toffee to the
cost of a chocolate.
3. In a school, there were 73
holidays in one year. What is the
ratio of the number of holidays
to the number of days in one year?​

Answer 1

Answer:

1) when you compare two quantities then you must make sure that both the quantities should be expressed in the same unit.

Time taken by Saurabh to reach school = 15 minutes

Time taken by Sachin to reach school = 1hour = 60 minutes

Now, the ratio of time taken by Saurabh to that taken by Sachin = 15 / 60

= 1 / 4

2) ⇒ Cost of toffee = 50 paise.

⇒ Cost of chocolate = Rs.10 = 1000 paise [ Rs.1=100 paise ]

⇒Cost of a toffee/Cost of a chocolate

= 50/100

= 1/20

∴ The required ration is 1:20

3) Number of holidays in a year = 73

Number of days in a year = 365

Number of holidays / number of days in one year = 73/365 = 1 : 5

the ratio of the number of holidays to the number of days in one year= 1:5

Hope this is helpful for you.
