Question

The price of gas was 2.85 yesterday and today it fell to 2.80. What is the percentage decrease?

Answer 1

I wanna move to wherever you live. I'm paying 3.15!!!

But whichever planet you're on, the drop here would be .05/2.85

The equivalent "percentage" is 100 times that.

Answer 2

No, I wish it was that cheap where I live but this unfortunately is just a math question that is on a quiz I am doing!!! I am terrible at math and have no clue how to figure this stuff out, hence the reason I am asking this!!! So it is .05% decrease then?! Thanks!

Answer 3

I'm paying 3.14 currently by the way!!! So we are not far apart on that one!

Answer 4

Now it says to round that to the nearest tenth?!

Answer 5

I'm a blonde in math!

Answer 6

No, it is not a .05% decrease.

Look at my comment again where I said "the drop here would be .05/2.85"

What is .05/2.85 ?

Answer 7

What about this one; a pancake recipe requires 2 and one quarter cups of milk and one cup of flour; how many cups of flour would you need if you used 3 and 3 quarters of milk? I put one and one half? Not sure!

Answer 8

Wait! We haven't even figured out the last one yet!!

What is .05/2.85 ?

Answer 9

Would it be a .02% decrease then? Do you divide .05 in to 2.85?

Answer 10

- "Do you divide .05 in to 2.85?"

No...that would be 2.85/.05 which is a relatively astronomical number.

Take your caculator and do this:

Enter the number .05
Hit the "divide" key.
Now enter the number 2.85
Hit the "=" key.
Tell me what the calculator says.

Answer 11

That's how I got .02% by dividing

Answer 12

I know it gives a large number if you type it in to the calculator the wrong way but the way I did it like your saying gave me .017

Answer 13

or I rounded and that where I got the .02 from!

Answer 14

That's not percentage. That's a decimal part. You need to convert the decimal to get a percentage.

But even then, .02 is a rounded decimal.

Answer 15

WAIT!!!

YESYESYES!!! The .017 is the number you're looking for!!!

Answer 16

Okay, so how do I convert it?!

Answer 17

But .017 is a decimal quotient. You still have to convert it into a percentage by multiplying it by 100.

Answer 18

1.7%

Answer 19

which makes sense!

Answer 20

BINGO!!!!! You got it!!!! :-)

2.80 is a 1.7% decrease from 2.85!!

Answer 21

Thank you!

Answer 22

No problem! Glad I was able to help! :-)

Answer 23

Okay, so what about the other question, do you think you can assist me with that?!

Answer 24

Sorry, I'm trying to answer 3 different problems here. :-)

So you mean the pancake one?

Let me look it over for a minute...

Answer 25

Yes and thanks!

Answer 26

Okay, so you can read it as the recipe calls for 2.25 cups of milk per cup of flour

That's the same as 1:2.25 or 1/2.25 as many cups of flour as milk.

1/2.25 = 0.444, so if you used 3.75 cups of milk you would need
.444 * 3.75 cups of flour

Answer 27

Okay, thanks!!!

Answer 28

No problem!! :-)
