This one to and the whole thing

4 5/8 the answer you have is correct :)

Step-by-step explanation:

First, you want to make the mixed fraction into an improper fraction.

 7 x 4 + 3 = 31 (31/4)

3 x 8 + 1 = 25 (25/8)

Now you want them both to have a common denominator.

31/4 x 2/2 = 62/8

Now you are ready to subtract!

62/8 - 25/8 = 37/8

Finally, convert 37/8 to a proper fraction.

37/8 = 4 5/8

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
