The Rule of Three Direct Teachris, by having three numbers given to find a fourts, which shall have the same Oroportion to the thiril, as tlie second has lutie first. 1. Cobserve that two of the given numbers in your question are always of the same name, or kind; one of which must be the first nymer in stating, and the on.co the third number : consequently, the first and third aume bers must always be of the same name, or kind: anıl the uther number, i hicho is of the saine kind with the answer. thing suylit, will always possess lie second or middle place. 2. Tlc iniril term is a demand ; and may be known: 'wy these or t.e like worls before it, viz. What will: What cost? How many? How für: llow long? ur, llow much : &c. RULE.' 1. State the question : that is, place the numbers so that the first and thire terins may be of the same kind and tie second term of the same kind with the answer, ur thing sought. 2. Bring the first and third terms to the same denone ination, and reduce t.e second term to the lowest name mentioned in it. 3. Multiply the second and third terms together, and diviele their product by the first term; the quotient will be the answer to the question. in the sanie cien.mination you left the second term ini, which may be brought into any odier (lenoinination required. The methodi vf proof is by inverting the question. NOTE.-T!: following methods of operation, when they can be usedl, perform the work in a much slurfer manner than the prosperiod rule 1. Diviste el second forin !y the first : multiply the quo. tient i ito the inirol, and the product will hr the answer (or 2.
