Solve Math Word Problems Online
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).
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.
You would be expected to understand that this meant that she worked eight hours for each of the four days Monday, Tuesday, Thursday, and Friday; and six hours for each of the two days Wednesday and Saturday.
Suppose you're told that Shelby earns "time and a half" for any hours she works over forty for a given week.
If a problems says "the ratio of Some times, you'll be expected to bring your "real world" knowledge to an exercise.
Probably the greatest source of error, though, is the use of variables without definitions.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. For instance, suppose you're not sure if "half of (the unknown amount)" should be represented by multiplying by one-half, or by dividing by one-half. Visual students will be keen on the ability to visualize math in this way, using the virtual blocks to represent word problems.* Use with the whole class using an interactive whiteboard or projector-connected computer.If the former, what does this mean, in practical terms?(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.* Students can take turns working out word problems on the whiteboard while students at their seats work to arrive at a common solution.The hardest thing about doing word problems is using the part where you need to take the English words and translate them into mathematics.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.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.
