Answer
9 hours : 9 days = 1 : 24
Step-by-step explanation
Before we do this, we need to convert 9 days into hours.
1 day = 24 hours
9 days = 9 (24 hours) = 216 hours
So, we can now reduce the ratio
9 hours : 9 days
= 9 hours : 216 hours
Divide both of them by 9
9 hours : 216 hours
= (9 hours)/9 : (216 hours)/9
= 1 hour : 24 hours
So,
9 hours : 9 days = 1 : 24
Hope this Helps!!!
