Answer 2

Answer:

Fixed answer: 7:56 PM

9:00AM/10:00AM

Step-by-step explanation:

Adding 12 hours to the current time has the effect of flipping AM to PM/PM to AM. Since 14 = 12 + 2 and 15 = 12 + 3, we can read "14/15 hours ahead" as an AM/PM flip, followed by adding 3/4 more hours. Following that here:

7:00 PM → 7:00 AM

7:00 AM + 2 hours/7:00 AM + 3 hours → 9:00 AM/10:00 AM

Fixed Response: 14/15 as a fraction

When I first answered this, I read 14/15 as "14 or 15 hours" instead of "14 fifteenths of an hour." Here's the explanation for that way of looking at it:

If we want to add 14 fifteenths of an hour to 7:00 PM, we first need to find what that is. Since there are 15 fifteenths of an hour in a whole hour, we can find 14 fifteenths by starting with one hour - 60 minutes - and taking away 1 fifteenth of an hour. 1/15 of 60 minutes = 60 ÷ 15 = 4 minutes, since 15 × 4 =  60. Subtracting those 4 minutes from 60, we find that 14 fifteenths of an hour = 60 - 4 = 56 minutes, and adding that to 7:00 PM gets us to 7:56 PM.
