In this task, you are given a context and four options. Each option is a suggested ending for the context. You should read the context and pick the best ending for the context. Please answer with "A", "B", "C", and "D".
Q: [header] How to find a fraction of a number [title] Write out the problem. [step] If the problem you are working with is a word problem, first you need to write out all of the numbers involved in the calculation. If you were given the numbers written out already, you can skip this step. <sep> (A) [substeps] A fraction of a number is one part of a fraction you created so that you can construct the fraction from scratch. For example, if you were given the numbers in a fraction of a set of numerators, you would write down that fraction again, and record, as you calculated the different fraction. (B) [substeps] If the problem you are working with is a word problem, chances are you will not need to worry about the terms. Let's say you are making the calculator more manageable by using code words for the problem. (C) The problem you must do is place the quarter from the fraction into an empty cell or. If you are working with a whole number, put the quarter from the fraction into the same cell, so the workable sum of all the numbers has equal value and is not taken away. (D) [substeps] For example: what is one-third of seven? When you see " of " written between two numbers in a word problem, think of it as meaning multiply. Thus, one-third of seven actually means one-third multiplied by seven.
