K I don't feel like doing this either so.

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)

The first and third.

Step-by-step explanation:

For the first one, you just subtract 52.37 and 46.37 and the answer is 6, so that makes the equation 6=y, which is right. The second one equals 6.75, so that's not what we need. For the third one, you divide by 8 on both sides to isolate y, and that results in y=6, which is right. For the fourth one you subtract by 3.2 on both sides to isolate y and that results in 5.8, which isn't what we need. I think for the last one you meant to type y=4+24, in which case that would be y=28, which isn't what we need.
