We will call the smaller integer n, and so the larger integer must be n 2 And we are told the product (what we get after multiplying) is 168, so we know: n(n 2) = 168 We are being asked for the integers Solve: That is a Quadratic Equation, and there are many ways to solve it.Using the Quadratic Equation Solver we get −14 and 12.
(And, if you can't think of any meaningful definition, then maybe you need to slow down and think a little more about what's going on in the word problem.) In all cases, don't be shy about using your "real world" knowledge.
Sometimes you'll not feel sure of your translation of the English into a mathematical expression or equation. For instance, if you're not sure if you should be dividing or multiplying, try the process each way with regular numbers.
Check There are now 16 boys and 12 girls, so the ratio of boys to girls is 16 : 12 = 4 : 3 At the start of the year there were 20 boys and 10 girls, so the ratio was 20 : 10 = 2 : 1 Consecutive means one after the other.
And they are even, so they could be 2 and 4, or 4 and 6, etc.
The hardest thing about doing word problems is using the part where you need to take the English words and translate them into mathematics.
Usually, once you get the math equation, you're fine; the actual math involved is often fairly simple.Suppose you're told that Shelby earns "time and a half" for any hours she works over forty for a given week.You would be expected to know that "time and a half" means dollars for every over-time hour.Below is a math problem solver that lets you input a wide variety of math problems and it will provide the final answer for free. The version below will show you the final answer only.You'll see a button "View steps" and this takes you to the developer's site where you can purchase the full version of the solver (where you can see the steps).Does "" stand for "Shelby" or for "hours Shelby worked"?If the former, what does this mean, in practical terms?Pick variables to stand for the unknows, clearly labelling these variables with what they stand for. You need to do this for two reasons: " stands for, so you have to do the whole problem over again.I did this on a calculus test — thank heavens it was a short test! (Technically, the "greater than" construction, in "Addition", is also backwards in the math from the English.Don't start trying to solve anything when you've only read half a sentence.Try first to get a feel for the whole problem; try first to see what information you have, and then figure out what you still need. Figure out what you need but don't have, and name things. And make sure you know just exactly what the problem is actually asking for.
