Answer the following questions.

serg [7]

39 is 312% of 12.5

To find this you just divide 12.5 into 39 which gives you 3.12. To change that to a percentage you multiply by 100 which gives you 312%

7.5 is 102% of 7.38

To find this you just divide 7.38 into 7.5 which gives you 1.0162, which I rounded to 1.02. To change that to a percentage you multiply by 100 which gives you 102%

I hope this helped! :)

Ezra is filling bottles of water to hand out during a race. Each bottle of water holds 16 ounces and he has 4,005 ounces of filt

Oksi-84 [34.3K]

So just by the question, we are aware that when we divide 4,005 ounces by 16, it is not going to be a pretty number - there are going to be some left over in the form of a fraction.

First we must find out how many of these bottles can be completely filled until there is only the small fraction left that is not able to fill up a bottle. So let's divide:

$\frac{4,005}{16}=250.3125$

And now we know that 250 bottles will be filled completely. To find the amount of ounces left over, let's see how many ounces 250 bottles is:

$250*16=4,000$

There are 4,000 ounces in 250 bottles. So we need to subtract our initial amount from this known amount:

$4,005-4,000=5$

So there are only 5 ounces of water remaining after 250 bottles are completely filled. To put this into a fraction of the original amount, we just divide by the initial amount (4,005):

$\frac{5}{4,005} =\frac{1}{801}$

If the question is asking for the remainder in terms of a bottle, we just divide these 5 ounces by the 16 ounces it would take to fill this bottle:

$\frac{5}{16}$
