Answer:
All these conversion factors are equal to 1. If it doesn't seem obvious at first, think about it for a second. Realize that 1 minute is equivalent to 60 seconds. Simply replace 1 minute in the fraction with its equivalent 60 seconds and it becomes clear that 60 seconds / 60 seconds = 1. Numerator and denominator are equivalent; they are just expressed differently.
Explanation:
The initial unit cancels out and goes into the new unit
In science, we often need to convert from one unit to another to ensure accuracy of our calculations.
Let's say i want to convert 500 minutes to seconds.
The conversion factor is as follows;
60 seconds make 1 minute
x seconds make 500 minutes
x = 60 seconds * 500 minutes/1 minute
x = 30,000 seconds
Hence the initial unit which is "minutes" is canceled out and the new unit "seconds" remains.
