See explanations below
Step-by-step explanation:
For us to know why 1/12 hour + 1/2hour=7/12hour, we will need to convert the hours to minutes and then add;
Since 1 hr = 60minutes
1/12 hr = 1/12 * 60 = 5minutes
1/2 hr = 1/2 * 60 = 30minutes
Add the right hand side
5minutes + 35 miutes = 40 minutes
Next is to convert 7/12hour to minutes
7/12 hrs = 7/12 * 60
= 7 * 5
= 35minutes
Since both sides gives 35minutes hence the equation given is true i.e 1/12 hour + 1/2hour=7/12hour
