Answer: 68 minutes or 1 hour and 8 minutes spent in all putting up the fence
Step-by-step explanation:
(4/5) x 60 = 48 minutes
4/5 is the same as 0.8, which is what you get when you divide four by 5
So, 0.8 x 60 = 48 is also acceptable
Then,
(1/3) x 60 = 20 minutes
1/3 is the same as 0.333333333333, which is what you get when you divided 1 by 3
So, 0.33333(and so on) x 60 = 20
- Typically, you can round 0.3333333 down to something like 0.333 which should give you a similar answer
Then, as it asks you for how much time he spent in all, you add those two together
48 minutes + 20 minutes = 68 minutes OR 1 hour and 8 minutes (There is sixty minutes in 1 hour, so subtract the 60 from 68 and then you have 8 minutes left, thus 1 hour and 60 minutes)
