*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.On the Modeling Tools tab, students will find modeling tool videos on addition and subtraction, multiplication and division, fractions, ratios, decimals and percents, and algebra.

If a problems says "the ratio of Some times, you'll be expected to bring your "real world" knowledge to an exercise.

For instance, suppose you're told that "Shelby worked eight hours MTTh F and six hours WSat".

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).

When you pick a letter to stand for something, write down explicitly what that latter is meant to stand for.

Does "" stand for "Shelby" or for "hours Shelby worked"?You would be expected to know that "time and a half" means dollars for every over-time hour.You'll be expected to know that a "dozen" is twelve; you may be expected to know that a "score" is twenty.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.So his normal pay of 40 × = 0, plus his overtime pay of 12 × = 0 gives us a total of 0 There are 12 girls!And 3b = 4g, so b = 4g/3 = 4 × 12 / 3 = 16, so there are 16 boys So there are now 12 girls and 16 boys in the class, making 28 students altogether.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.And "volume" is the insides of a three-dimensional shape, such as a cube or sphere (so you'll probably be multiplying).Probably the greatest source of error, though, is the use of variables without definitions.
