Solution:
Concept: In order to obtain the ratio of 10 hours to a day, we must first convert a day into the number of hours so that the numerator and denominator of the ratio or fraction have the same units. We are unable to solve the fraction without the same units. According to this unit definition, 1 day equals 24 hours, we shall convert a day to hours. The ratio will then be made simpler by eliminating any shared variables from either the numerator or denominator, if applicable. And we'll learn the response.Finding the ratio of 10 hours to a day is necessary. This can be done by writing 10 hours: 1 day. Now, by fractionalizing it, we have,
We know that in order to simplify any fraction, we must first change the numerator and denominator's units to match. Since 1 day = 24 hours, we may do this.When we use the aforementioned fact in our equation, we obtain
Ratio = 
Hence, the correct answer is option 1.
