Riddle Me This

A fish weighs 4lbs. plus 1/4 of its weight. How much does the fish weigh?

Protip: If you say 5lbs you need to be screened for late onset downs.

It weighs 4lbs. plus 1/4 of its weight.

FUCKING JANITORS REMOVE THIS SHIT BEFORE RED DIT UPVOTES THIS TEN TIMES

sixteen thirds of a pound. fucking elementary.

4/1-4(72)-13=5

you're wrong

5 lbs of slide material

5
>did I get it?

wolframalpha.com/input/?i=4 + 1/4x = x

Let x be the weight of the fish in pounds.

The fish weighs 4 pounds plus 1/4 of its weight:
x = 4 + (1/4)x

-> x - (1/4)x = 4
-> x(1 - 1/4) = 4
-> (3/4)x = 4
->.x = 4(4/3)
-> x = 16/3

The fish weighs 16/3 pounds.

Now fuck off.

7 lbs.

4 + 1/4x = x

x = 3

4 + 3 = 7

Reddit

It always weighs 4 pounds because 1 pound of fish weighs the same as 1 pound of anything else.

What he said I got ddos'd when I switched the 3/4.

These are correct.

STOP REPLYING TO THESE FUCKING SLIDE THREADS YOU FUCKING MORONS

OH MY GOD WTF IS THIS RIDDLE ITS FUCKING 5 RIGHT?!?!

x = 4 + 1/4x
4x = 16+ x
3x = 16
x = 16/3

no

lol

Practically, i honestly dont understand this. I get why its mathematically 16/3 but intuitively it REALLY fucking seems like the answer is 5 pounds and i dont understand why its not.

...

...

Let f be the fish

f = 4 + (1/4)f

Subtract (1/4)f from both sides.

(3/4)f = 4

Multiply by 4.

3f = 16

Divide by 3.

f = (16/3)

its a riddle everyone seems to be missing the point

THE FISH WEIGHS 5.33333333333 POUNDS


SLIDE THREAD SAGE SAGE SAGE

because the way the question is presented
he wants you to think it's weight is 4 lbs so you want to just add 1

The question is basically "The fish's weight its equal to 4 plus one forth of the fish's weight." The question is worded so it makes it sound like the fish's weight is already 4 and then has one forth of the weight added on.

This is like that troll post that claims .999 = 1

It weights 4.25 poundarinos
People in this thread are so fucking dumb. Hope in humanity LOST

If the answer is "4 pounds" because there's a period after the first sentence, im going to fucking scream.

It's fucking stupid.

Also. >1 post by this ID

:)

>he fell for the 16/3 meme

The first thing he said is that the fish wieghs 4 pounds. Saying that it equals its weight plus a fraction of its weight makes no sense (4=4+(.25*4)) so 4

It is 8. Parentheses go first.

SAGE AND REPORT OFF TOPIC THREADS

x = 4 + (1/4x)
x = 16/3 or 5.33

OP IS A NIGGER

ÅÍÎÏ©ÓÔÂÔ¨¶§∞¢£™¡Œ£¢£§¶•ªº

This is the kind of riddle math nerds should tell their math nerd friends on their math nerd forums. I have no idea why they are so popular on Sup Forums

Parentheses

THEN

Exponents

THEN

Multiplication AND division

THEN

Addition AND subtraction

Because it isn't set up properly in the mathematical sense.

What we have seen in this thread is

Fishweight = 4 + 1/4(Fishweight)

What the question ACTUALLY asks is

Fishweight = Fishweight + 1/4(Fishweight)

If Fishweight is equal to 4, like OP says, then

4 = 4 + (1/4)4
4 = 5

Therefore, the only real possible value for fishweight is zero.

Simplify your answer

>simplify your answer

There aren't enough 1s and 0s floating around the internet to draw out that many 3's you autistic cunt

>African """education"""
Real close Nelson.
X = 4 + 1/4x
X's cancel out
4+1/4
4.25

it weighs 4 pounds, sempai. you said so yourself.

>X's cancel out

You weigh 300 pounds. You weigh 200 pounds + 1/3 of your total weight, which is 100 pounds. It's not that hard.

They don't teach fractional notation in SA?

You can't divide 4 by X you fucking nigger.

Why the fuck are you doing this ? Why post this here

5 & 1/3

If I weigh 200 lbs + 1/3 of that i only weight 266.6 lb u dumb shit

There was another thread where the question was a ticket costs $1 plus half of its cost, how much does the ticket cost, and 90% of you yards couldn't answer correctly. Figured you need more practice.

What are you even talking about you dumb shit.

>ask nonsensical question
>get nonsensical answers

It is a mystery.

what's up with these math quizzes

What the fuck? The fish has an exponential weight.

4 * 1.25 = 5
5 * 1.25 = 6.25
6.25 * 1.25 = 7.8125
7.8125 * 1.25 = 9.765625
and so on

2 X's don't just cancel out. You would still have:

1= (4/X) + (1/4)

Sage + Report = dead slide thread unrelated to politics.

>X = 4 + 1/4x
>X's cancel out
>4+1/4
That is not actual math.

Trump won dickhead take a day off.

Did you actually pass algebra?

You're clearly less educated than you are confident. This is primary school level stuff (or high school if you're an idiot).

Let x be the fish's weight:

x = 4 + x/4
x - x/4 = 4
4x - x = 16
3x = 16
x = 16/3

1/4 of 4 is 1. 4 + 1 = 5
You faggots need to lay off the core math.

retard burgers

Who ever said that the wish's total weight was 4? 1/4 of X ≠ 1/4 of 4.

Literally where?

A fish does not have fingers therefore it cannot weigh anything out, and if i do not know the fish's weight I cannot answer the question.

>A fish weighs 4lbs

BEGONE BUTT BANDIT!

correct answer, /thread

Never!

Maybe if you finished the thought it would make more sense.

>A fish weighs 4lbs PLUS 1/4 of it's (total) weight

Therefore

F = 4 + 1/4F

Do all fish weigh 4lbs? What if it's a bigger fish?

...

I got ddos'd it happens to the best of us. When I switched the 3/4, I left it so, instead of it being 4/3, which is why I ended up with 3, and not 16/3 like I should have.

Ok you mus the really young or really ducking dumb I'd gou don'5 know algebra

He even closes off the sentence with a period. Plus 1/4th of the fishes weight? Not really a sentence. If he said plus 1/4 it would be 4.25, but he specifically says plus 1/4 of the fishes weight which would be 1.

BEGONE BUTT BANDIT

It weighs 125%

You just told me it weighs 4 lbs.

a weight is a weight. You can't say it's only a half

A period finished the thought and completes the sentence. I can't help it if you failed reading comprehension.

BEGONE BUTT BANDIT!

I didn't close the sentence I was punctuation the abbreviation for pounds lbs.

>Closing a sentence is the only use for a period

What are abbreviations?

>A fish weighs 4lbs.
>How much does the fish weigh?

4lbs

You're all fucking wrong.

You can't weigh something of your total weight PLUS some fraction of your total weight.

You're all idiots. The answer is impossible.

Begone butt bandit!

Weight x = x/4 + 4
4x = x + 16
3x = 16
x = 16/3 lbs.
The answer is easy to reach intuitively but hey maybe some of you are morons so here's the step by step.

What are they trying to slide right now?

>Assuming 4 is the total weight

Nigger, we already went over this. I'm sorry schools in Detroit aren't good but this isn't the time for that.

This is cancer in a post. Lrn 2 engrish.

The fuck is there to hide anymore. Trump won.

It still doesn't change anything. If you want to word it like some ++ operation, it would continue incrementing by 1/4 indefinitely.
>1/4 of its weight
does not equal .25

>Assume
>Clearly stated by faggot OP
You went over it and we're too fucking dumb to comprehend it.

Go back to your rural shit hole of an education, sister fucker.

>A fish weighs 4lbs.
Ok. That's your answer. What are you saying about half it's weight though?

It doesn't say plus 1/4 of it's total weight
