The Rule of Three Direct teaches by having three numbers given to find a fourth, which shall bear such proportion to the second as the third doth to the first; and is that in which more requires more, or less requires less. RULE.-State the question by making that number which asks, the third term ; that which is of the same name or quality as the first term ; and that which is of the same name or quality with the answer required, the second term. Then multiply the second and third terms together, and divide the product by the first. The quotient will be the fourth term or answer, in the same name or denomination as the second term was left in. Note-The first term is always known by the words if, or at; and the third term is also known by the words how much, or what will. EXAMPLES. 1.
