In the following example, the question asks you to determine the total number of socks between the two sisters.
The unit of measurement for this problem is pairs of socks.
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.

(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. Does "" stand for "Shelby" or for "hours Shelby worked"?If the former, what does this mean, in practical terms?"Suzy has eight pairs of red socks and six pairs of blue socks. If her little sister owns nine pairs of purple socks and loses two of Suzy's pairs, how many pairs of socks do the sisters have left?" Create a table, list, graph or chart that outlines the information you know, and leave blanks for any information you don't yet know.Begin by determining the scenario the problem wants you to solve. Either way, the word problem provides you with all the information you need to solve it.Once you identify the problem, you can determine the unit of measurement for the final answer.You'll also be expected to know that "perimeter" indicates the length around the outside of a flat shape such as a rectangle (so you'll probably be adding lengths) and that "area" indicates the size of the insides of the flat shape (so you'll probably be multiplying length by width, or applying some other formula).And "volume" is the insides of a three-dimensional shape, such as a cube or sphere (so you'll probably be multiplying).— and, trust me, you don't want to do this to yourself! Certain words indicate certain mathematica operations. But the order in addition doesn't matter, so it's okay to add backwards, because the result will be the same either way.) Also note that order is important in the "quotient/ratio of" and "difference between/of" constructions.If a problems says "the ratio of Some times, you'll be expected to bring your "real world" knowledge to an exercise.
