When I deal with a math problem how can I deside that the problem's solution require a division?

Solve the inequality the same way you would any other equation. Just remember that when dividing or multiplying by a negative number you have to flip the inequality.

You can cross-cancel, and then multiply ... at least I think that's what it's called. \n\nLet's say you have the problem 27/4 x 16/9. Looks somewhat large at first, but you can make it really simple. The 9 and 27 can be reduced, because 9 is a factor of both of those numbers. Take 9 out of each and you get 3/4 x 16/1. Then you can take 4 out of the 16 and the 4. You're left with the problem 3/1 x 4/1, which equals 12/1. That reduces to 12.\n\nA long-looking problem that can be easily simplified. Hope that helps.

All area, wherever you go..you will use that algebra for your work. For example, the simple one, if you are working in the service company, and you have to make a report of the percentage of total complaint you receive a day...\nYou have to use your algebra.\n\nDon't ever think it's pointless..., otherwise you will hate it and later on you will regret it, that you don't pay too much attention to that subject

Practice.  First off, you have to show ALL of your work.  If you can't write it down, you don't understand.  Saying "I do it in my head" doesn't cut it.  Explain how to do a problem that you already know how to do to someone else.  Mathematical concepts are cumulative so you have to understand how to do one type of problem before moving on to the next.\n\nI know that most math textbook, especially grade school, have too many review problems and not enough problems dealing with the new concept being introduced.  Therefore do all of the homework problems, not just those assigned.  After you get papers back, figure out why you didn't get the correct answer on those you missed.  What step did you miss?  Did you make a mistake in arithmetic?  Did you miss a critical piece of information needed to solve the problem?  Did you try to use some information that really wasn't needed?\n\nThe biggest problem most people have with math is that they think that they have to get the answer right away.  That is fine for simple addition and subtraction.  But think about long division.  If you follow the process and don't rush, it may take awhile but the answer eventually comes.  Same idea goes for simplifying algebraic equations, doing trigonometry proofs, solving quadratic equations, calculus derivatives, integrals, and differential equations.  Take is slow, do what you know, and figure out what you don't.

You can't divide by 0, you can divide anything by 1, you can divide any even number by 2 to get a whole number,...etc. This website has more divisibility rules: \nhttp://mathforum.org/k12/mathtips/division.tips.html

Mathematics builds, from simple to complex.\n\nHaving said that, the complex problem you are working may have a solution or may be not. Break down the problem into all the know facts leading to an answer.\n\nWord problems test your understand of mathematical principles and how to applied them.\n\nBe patient and good luck.

My old math teacher showed me this.\n\nSince A=B, then A-B=0, and you can't divide by 0

"Look up the word 'divide'. You cannot divide something by either 0 or 1, ever."\n\nHow about you try a MATHEMATICAL definition of divide.  In math, division by n is defined as multiplication by the inverse of n (usually denoted n^-1 but I'll call it 1/n due to the lack of superscripts).  You are absolutely right that you can't divide by zero.  However, it has nothing to do with splitting into parts.  The multiplicative inverse of n is defined as the number 1/n such that n*(1/n) = 1.  It is a property of 0 that anything times 0 equals 0, therefore the multiplicative inverse of n canot exist.  Thus it is impossible to divide by 0.\n\nDividing by 1, however, is a perfectly legitimate mathematical operation although it tends to be unproductive.  Because 1x1=1, the multiplicative inverse of 1 is 1.  From the definitions above, division by 1 is the same as multiplication by 1, which is most certainly an acceptable mathematical opperation.

i am sure you can find a math tutor that will be happy to help you when you explain what the problem is.\n\nso what IS the problem, anyway?

Division, if you do not know how to divide can be done easily.\n\nTake the problem 32 divided by 8.  You would divide this out the long way.  The easiest way might be to subtract 8 until you get to zero.   You notice it take you 4 times of subtracting 8 to get to zero.  So your answer would be 4.

There's a mathematical riddle that claims to "prove" 1 = 2, but if you examine it closely enough, it turns out to be dividing by 0.  Sorry I csn't remember the riddle.

Why do you need it?\n\nDo you mean divide?

Need to say what you are doing with the problem: solving for x, solving for y, other?\ny=(3/2)x+(7/4)

Your computer has a calculator built in.  Failing that, try long division.  You're gonna have to learn how to do it anyway.\n\nSheesh.

Schools should teach that you can't divide by zero. 20/0 is an insolvable problem. 0/20 is 0.

The KEY to solving any algebra problem, as I tell my students, is to get your unknown variable all by itself on one side of the equal sign.\n\nYou do this by "undoing" everyingthing that's being done to it right now.  And you "undo" the easy stuff first, like addition and subtraction, and then the more complicated stuff like multiplication and division.\n\nSo if you're adding 3 to X, then you would subtract 3.  And remember, what you do to one side of the equal sign, you MUST do to the other, so you would need to subtract 3 from both sides in my example.
