calm nimbus Struggling with a worded question

I don't really understand what it's asking for

calm nimbus Apr 21, 2023, 4:54 AM

#

Neither

#

Teacher isn’t getting back to me on this

hybrid tapir Apr 21, 2023, 5:43 AM

#

calm nimbus Neither

I think it's asking for the 2nd to last sentence:
"...the barrel finally contains..."

clever flint Apr 21, 2023, 6:21 AM

#

It's asking us for how much water, in litres is left in the barrel

#

it also states that the amount of water left in the barrel at the end is equal to a fraction of the capacity of a bottle

#

the answer is 0.5 litres

calm nimbus Apr 21, 2023, 6:32 AM

#

But I have to find this out using fractions?

#

Do I just use 26/1.5=x+0.5

#

It does make use of fractions but, it also uses decimal points. The question says I “can’t use decimal number expressions”

clever flint Apr 21, 2023, 6:34 AM

#

calm nimbus Do I just use 26/1.5=x+0.5

you can't use this either way because 0.5l is the answer

#

you can;t use it in ur solution

calm nimbus Apr 21, 2023, 6:35 AM

#

Hmmm

clever flint Apr 21, 2023, 6:35 AM

#

0.5l is what you are trying to work towards

calm nimbus Apr 21, 2023, 6:35 AM

#

It’s easy to get the answer but I can’t figure out how to explain it using fractions

clever flint Apr 21, 2023, 6:36 AM

#

well id say u have to use logic

#

26/3/2 = x

#

x=52/3

#

the number of times 3 can be divided into 52 is 17

#

so there are 17 people

calm nimbus Apr 21, 2023, 6:37 AM

#

17.333

sinful burrow Apr 21, 2023, 6:37 AM

#

@calm nimbus basically have to answer many 3/2 can you fit in 26. And what fraction of the bottle is the water that remains.

clever flint Apr 21, 2023, 6:37 AM

#

yes but you wouldn;t say there are 17.333 people

calm nimbus Apr 21, 2023, 6:37 AM

#

Would it be okay to round it?

#

Would that not affect the outcome?

clever flint Apr 21, 2023, 6:38 AM

#

not in this case

#

it's the amount of times 1 bottle is completely filled

calm nimbus Apr 21, 2023, 6:38 AM

#

Forgot about that

#

Right

#

Fuck how would I write that

#

In an equation format

clever flint Apr 21, 2023, 6:44 AM

#

you would solve for number of times the bottle was completely filled then find out how much water was left. x = number of times bottle was filled, y= leftover water. x=52/3, y= 52/3x

hybrid tapir Apr 21, 2023, 6:44 AM

#

if I understand correctly then the working should be like this:
26/(3/2) = 52/3 ≈ 17 hikers
26-17×(3/2) = 1/2 litres (water left in barrel)

calm nimbus Apr 21, 2023, 6:45 AM

#

26x2/3 = 52/3 = 17+1/3 rounded to 17
17x1.5=25.5, 25.5-26= 1/52 of water left

clever flint Apr 21, 2023, 6:45 AM

#

26-25.5

#

not 25.5-26

sinful burrow Apr 21, 2023, 6:45 AM

#

Wait wut

calm nimbus Apr 21, 2023, 6:45 AM

#

clever flint 26-25.5

They both mean the same thing, you can take the negative and turn it to a positive for the sake of the equation

#

I can rewrite it like that though yes

clever flint Apr 21, 2023, 6:46 AM

#

no

hybrid tapir Apr 21, 2023, 6:46 AM

#

26-25.5=1/2 not 1/52

clever flint Apr 21, 2023, 6:46 AM

#

you wouldn't say I have negative 0.5l

sinful burrow Apr 21, 2023, 6:46 AM

#

@calm nimbus it is 1/3 of the bottle therefore 1/3*3/2=1/2

calm nimbus Apr 21, 2023, 6:46 AM

#

hybrid tapir 26-25.5=1/2 not 1/52

Ah right

#

Yeah my bad

calm nimbus Apr 21, 2023, 6:47 AM

#

clever flint you wouldn't say I have negative 0.5l

I’ll take your word for it

#

Even still, I can’t use any decimals

#

So I’m good up until 17x1.5

#

17 x 3/2 = 51/52?

sinful burrow Apr 21, 2023, 6:49 AM

#

You have to interpret what you write 17 +1/3 means 17 whole bottles + 1/3 of a bottle

calm nimbus Apr 21, 2023, 6:50 AM

#

Yeah

calm nimbus Apr 21, 2023, 6:50 AM

#

calm nimbus 17 x 3/2 = 51/52?

Would this be correct?

clever flint Apr 21, 2023, 6:53 AM

#

calm nimbus Would this be correct?

no

calm nimbus Apr 21, 2023, 6:53 AM

#

Aaaaaaaaaa

clever flint Apr 21, 2023, 6:53 AM

#

17 times 3 divided by 2

#

from left to right

calm nimbus Apr 21, 2023, 6:54 AM

#

17 x 3 over 2, meaning 1.5

#

But as a fraction

hybrid tapir Apr 21, 2023, 6:54 AM

#

calm nimbus 17 x 3/2 = 51/52?

51/2

calm nimbus Apr 21, 2023, 6:54 AM

#

Oh that’s good

#

Alright

#

I have one more question on this assignment

#

#

Also worded

sinful burrow Apr 21, 2023, 6:58 AM

#

@calm nimbus What was you answer to that (just to make sure)

#

I mean the previous problem

calm nimbus Apr 21, 2023, 7:00 AM

#

26 x 2/3 = 52/3 = 17+1/3 rounded to 17.
17 x 3/2 = 51/52
51/2 where 2 is equal to 1 litre.
The remaining water is equal to half a litre.

136000 = x + 3x/5 + (3x/5)^2 + (3x/5)^3

sinful burrow Apr 21, 2023, 7:03 AM

#

@calm nimbus Ok that is right but from 26/(3/2)=52/3=17+1/3 you can straight up say 17 whole bottles where filled and 1/3 of a bottle remains. So 1/3 of a bottle=1/3*(3/2)=1/2 litres

clever flint Apr 21, 2023, 7:03 AM

#

clever flint 136000 = x + 3x/5 + (3x/5)^2 + (3x/5)^3

solve for x then sub x into (3x+5)^3

for your answer

I could have shortened it yes, but I had already written stuff and didn’t feel like crossing off half of the question response area

calm nimbus Apr 21, 2023, 7:04 AM

clever flint solve for x then sub x into (3x+5)^3

Also thank you very much

Thank you all

also I have no idera how to solve that

I think I can solve it

clever flint 136000 = x + 3x/5 + (3x/5)^2 + (3x/5)^3

I don’t think this is written correctly

Are you sure?

It works

calm nimbus Apr 21, 2023, 7:15 AM

oh god

I see my mistake

What was it?

clever flint Apr 21, 2023, 7:16 AM

#

clever flint 136000 = x + 3x/5 + (3x/5)^2 + (3x/5)^3

1360000 = x + 3x/5 + (3x/5)^2 + (3x/5)^3

#

I wrote plus 5 it should of been over 5

calm nimbus Apr 21, 2023, 7:17 AM

#

Oh haha

clever flint Apr 21, 2023, 7:17 AM

#

clever flint

anyways according to this website, this is the answer

calm nimbus Apr 21, 2023, 7:17 AM

#

Was it the +5 on both examples?

clever flint Apr 21, 2023, 7:18 AM

#

clever flint

here I wrote the correct equation

calm nimbus Apr 21, 2023, 7:18 AM

I see, thank you

Any idea why it’s not working? Have I written something wrong but don’t see it?
