Find the ratio of 30 sec into5 min?

Answer 1

30 sec : 5 mins.

Remember in one minute there are 60 secs.

So in 5 mins there are 5 x 60 = 300 secs.

Hence the ratio is

30: 300

This will reduce by '10' to

3 : 30

This will reduce by '3' to

1 : 10

So the ratio of 30 sec : 5 mins is 1:10

Mathematically/algebraically this would be written as

30 sec : 5 min :: 1 : 10

Note the use of the colon and the double colon.
