Answer 2

Answer:

The ratio of 2 hours to 45 seconds is 160 : 1.

Step-by-step explanation:

Given:

The given hour is 2 hrs.

Secounds = 45 sec

To find: ratio hours and seconds

Solution:

The given hour is 2 hours

Therefore,  we know that 1 hour = 60 minutes = 3600 seconds

Similarly, 2 hours = 120 minutes = 7200 seconds

Now,

Equating the data, we get

∴ 7200 : 45

=> 160 : 1

Hence, the 2 hours to 45 seconds in the simplest ratio is 160 : 1. Ans

Explanation:

The above solution is the simplest way to answer the examination question. Here, In the question, it is clearly asking for the ratio between 2 hours and 45 seconds. So, at first, we have to focus on the unit part as we have seen that at one side hours are given and on other seconds. So, we need to convert the hour into second. Therefore, the 2 hours are converted into seconds. We know that in 1 hour there is 60 minutes and also 1 hour is equal to 3200 seconds. So, Calculate the same for 2 hours. Hence,  In 2 hours there is 7200 seconds Now, The 2 hours is converted into seconds and our question is also in seconds. Therefore the only thing now we need to do is to equate 7200 seconds to 45 seconds. In next step divide the equation by 45 both side as wee see that 7200 is a factor of 45. Else we need to bring the equation into simpliest number which cannot be divided further. So at the end by dividion we get an answer 160 : 1
