...also have mc > nd, then a/b = c/d. The definition given by Eudoxus may thus be rephrased as follows: The ratio of a to b is equal to the ratio of c to d if, whatever multiples ma and mc are chosen, and whatever multiples nb and nd are chosen, then either... | |

...manipulate ratios given a set of constraints. Let A, B, C, and D be positive integers. Assume that the ratio of A to B is equal to the ratio of C to D. Find a possible value for A if the product of BC = 24 and D is odd. SOLUTION The quickest way to find... | |

...D, having such values that B=D A C' then A is said to have the same ratio to B that C has to D, or the ratio of A to B is equal to the ratio of C to D. "When four quantities have this relation to each other, compared together two and two, they are said... | |

To express that the ratio of A to B is equal to the ratio of C to D, we write the quantities thus : A : B : : C : D; and read, A is to B as C to D.
