5 points as a welcome back ! DS

It is very good I like it it made me chuckle lol

. I'll be happy to do it once I get access to the laptop.

. I think that's the wrong question, I just done it.

That is excellent MG

Do you want to do my original question now MG.

You could even do it in LaTex :)

$$\\34\frac{1}{8}\times \frac{14}{51}\div 1\frac{15}{34}$$

When you finish, check it on the forum calc :)

221/10

As a mixed number.

10 fits into 221, 22 times with a remainder of 1.

22+1/10

I'll do the algebraic question (1st comment) once I have access to my computer so I can do latex

$${\frac{\left({\mathtt{34}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{8}}}}\right){\mathtt{\,\times\,}}\left({\frac{{\mathtt{14}}}{{\mathtt{15}}}}\right)}{\left({\mathtt{1}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{15}}}{{\mathtt{34}}}}\right)}} = {\frac{{\mathtt{221}}}{{\mathtt{10}}}} = {\mathtt{22.1}}$$

Yes I think so too.     

Write it as a fraction  19/58  then multiply by 100 and put the percent sign 

$$\\4sin^2x+2cos^2x-3=0\\
4sin^2x+2[1-sin^2x]-3=0\\
4sin^2x+2-2sin^2x-3=0\\
2sin^2x-1=0\\
2sin^2x=1\\
sin^2x=\frac{1}{2}\\
sinx=\pm\;\frac{1}{\sqrt2}\\
x=180n\pm\;45\quad degrees\qquad n\in Z \qquad $ (n is an integer)$$$

That is great MG

BUT

it is an improper fraction I want a mixed numeral for the answer.

Since it is really easy you could give the decimal answer as well.:)

--------------------------------------------

this is the question you have answered - it is a little different from the question that I asked.

$$\\34\frac{1}{8}\times \frac{14}{15}\div 1\frac{15}{34}$$

and this is how you would put it into the forum calc.

(34+1/8)*(14/15)/(1+15/34)        

You have to put this in the calculation box of course 

I want you to use the calc to check that your answer is correct  :)

Surely, when the first cannibal gets back, (sentence 1), there will be three cannibals and two photographers, so it's dinner time ?

If they are not hungry, when two of them have crossed the river there will be two cannibals and one photographer on the bank, and they must be hungry by now ?

13/2*1/5

13*1=13

2*5 = 10

13/10*17/1

13*17=221

10*1 =10

221/10 is the answer.

I was going to say ten but then that's 2 digits so I said 0. 

Ill keep note of that! 

:)

That is good MG although technically 0 is not a multiple of 2  :))

Yes, that is excellent MG, can you finish it off  and then check it onthe forum calc in the same posts?

------------------------

then

You can work out WHY you have not answered the original question that I asked and answer that one :))   [You made a copy error]

 rosala and melody are right.

Just like to point out, the last digit has to be a multiple two, to be divisible without a decimal.

(2, 4, 6, 8, 0)

273/8 * 14/15 * 34/49.    /2. (8,34)

273/4 * 14/15 * 17/49    /2. (4,14)

273/2 * 7/15   * 17/49.  /7. (7,49)

273/2 * 1/15   * 17/7.   /3. (273,15)

91/2. *  1/5.    * 17/7.   /7. (91,7)

13/2.  * 1/5.    * 17/1.  

Lol they are all prime numbers now...1 mathematically not but .

Sorry to the cheap presentation I'm using my kindle. :(

I hope it's clear in the brackets is what's being divided by the number  /x.

You are still a good friend to DragonLance aren't you Rosala.

Loyalty is a good thing.       

A number is divided by 3 and leaves a remainder of 3. What numbers could it be?

You are right MG     

If you divide a whole number by 3 you cannot have a remainder of three it does not make sense.  The remainder would have to be 0,1,or 2

You can divide by 2 but there will be a remainder of 1.

Only even numbers can be divided by 2 with no remainder.

Nice working rosala.

But I'm puzzled on something, I was going to do what you about 30min ago.

You figured out that three, threes ffit into nine but anon wants to know what can go in three times with a remainder of three.

I'm probably wrong, I'm rubbish at questions worded like this...

Haha CPhill.

You're being modest, I haven't seen one question that you've failed to answer!

$${\mathtt{\,-\,}}\left({\frac{{\mathtt{22}}}{{\mathtt{35}}}}{\mathtt{\,\times\,}}\left(-{\mathtt{35}}\right)\right) = {\mathtt{22}}$$

Or this:   $${\mathtt{\,-\,}}\left({\frac{{\mathtt{22}}}{{\mathtt{35}}}}{\mathtt{\,\times\,}}{\mathtt{x}}\right) = {\mathtt{35}}$$       =>    $${\mathtt{x}} = {\mathtt{\,-\,}}{\frac{{\mathtt{35}}{\mathtt{\,\times\,}}{\mathtt{35}}}{{\mathtt{22}}}}$$       

      x =      $${\mathtt{\,-\,}}{\frac{{\mathtt{35}}{\mathtt{\,\times\,}}{\mathtt{35}}}{{\mathtt{22}}}} = {\mathtt{\,-\,}}{\frac{{\mathtt{1\,225}}}{{\mathtt{22}}}} = -{\mathtt{55.681\: \!818\: \!181\: \!818\: \!181\: \!8}}$$

no it can not be divided by 2 as if any number has to be divided by 2, it needs to have a 2 or its any multiple at the end...and in this number i can see none!

I dont think i should be saying something on this but i would like to....

The thing is , rude was it?yea i guess direct words really arent very pleasing so i kinda found it rude too.....but i would just say if you dont like someones post just say with some bended words.....that wont hurt or sound any bad.....

i liked your theory DL.......points for you!
