SIMPLE PROPORTION,

OR

THE SINGLE RULE OF THREE.

Four numbers are said to be proportional, when the first contains the second, or some part of the second, as often as the third contains the fourth, or a like part of the fourth.

In questions which are solved by Simple Proportion, three terms of a proportion are given to find the fourth.

RULE.

Write down, for the third term, that number which is of the same name or kind with the answer.

Consider, from the nature of the question, whether the answer should be greater or less than this third term. It it is to be greater, set the greater of the two remaining numbers on the left hand, for the second term, and the other for the first; but if less, set the less of those two numbers for the second, and the other for the first.

When the question is thus stated, if the first and second terms be not of the same denomination, reduce one or both of them till they are; and if the third term consist of several denominations, reduce it to its lowest denominalion; then,

Multiply the second and third terms together, and divide the product by the first term: the quotient will be the answer.

Note. The product of the second and third terms is of the same denomination a the third term; and the learner may be reminded, that the quotient and remainder are of the same denomination as the number divided.

See examples 14, 15 and 16, under rule 1, and 7, 8, under rule 3, Compound Division.

The rule which is given above, as it renders the distinctions of direct and interse proportion unnecessary, and has several other advantages, is preferable to the one which was formerly used; and it is likely to be generally adopted: but, for the convenience of those teachers who have not yet determined to employ it, the last mentioned rule is subjoined.

RULE FOR STATING.

Set that term of the supposition which is of the same name or kind with the term of demand, in the first place; set the other term of supposition in the second place, and the term of demand in the third place.

When the question is thus stated, consider whether the proportion is direct or inverse.

The proportion is direct, when the third term is greater than the first, and the nature of the question requires that the fourth term, or answer, should be greater than the second; or when the third term is less than the first, and it is required that the fourth term be less than the second.

The proportion is inverse, when the third term is greater than the first, and the fourth is to be less than the second; or when the third term is less than the first, and the fourth is to be greater than the second.

RULE FOR DIRECT PROPORTION.

If the first and third terms be not of the same denomination, reduce both to the lowest in either; and if the second term consist of several denominations,
