Related termsLatinFrom Wiktionary under the GNU Free Documentation License. In mathematics, a ratio expresses the magnitude of quantities relative to each other. Specifically, the ratio of two quantities indicates how many times the first quantity is contained in the second and may be expressed algebraically as their quotient. Notation and terminologyThe ratio of quantities A and B can be expressed as:
The quantities A and B are sometimes called terms with A being the antecedent and B being the consequent. The proportion expressing the equality of the ratios A:B and C:D is written A:B=C:D or A:B::C:D. Again, A, B, C, D are called the terms of the proportion. A and D are called the extremes, and B and C are called the means. The equality of three or more proportions is called a continued proportion. From Wikipedia under the

Q. 10th Grade Biology, my text book says o this is the ratio for this and this is the ratio for this but it doesnt explain how to figure out the ratio myself. Can anyone please help explain how you determine the ratios for the heterozygous and homozygous stuff? Asked by Luke - Tue Feb 2 16:39:57 2010 - - 2 Answers - 0 Comments A. Ratios are nothing more than fractions withthe denominator removed IF the denominators are all the same, so if 1/4 are BB, 2/4 are Bb, and 1/4 are bb, the ratio is 1/4 : 2/4 : 1/4 or 1:2:1. If 7/16 are one phenotype and 9/16 are another, the final ratio is 7 : 9. If there are 12 offspring and 6 are Gg and 6 are gg, then the fnal ratio is 6/12 : 6/12 or 6:6, which reduces to 1:1. Answered by Asst Prof - Tue Feb 2 17:13:23 2010 What is meant by the stoichiometric ratio in relation to gasoline engines? Q. As far as I know, gasoline consists of a blend of several different hydrocarbons which are extracted from raw petroleum. In chemistry the stoichiometric ratio would refer to the the number of mols of each reactant required to make the reaction a balanced equation (or else it would violate the law of conservation of matter) That being said different hydrocarbons would have different stochiometric ratios with the atmospheric oxygen when they combust. So my question is this: How can their be a single value which is considered 'stoichiometric' for gasoline? Asked by mathiusdragoon - Fri Mar 20 13:06:31 2009 - - 2 Answers - 0 Comments A. Short answer: The value varies based on things such as temperature of the incoming air, rpm versus load, etc. While 14.7:1 is ideal for an 'ideal' situation, cars frequently shoot for a different ratio depending on conditions. The ratio itself can and does get lost sometimes in the logic. The more the throttle is held in a certain position, the closer and more likely the car is to run at 14.7:1.

Q. I have two piece of plastic. One is .003cm thick, the other is .004cm. I need a ratio to express the difference in thickness, and a calculated value for the difference. How do I go about this? Asked by Maria - Sat Oct 28 12:04:18 2006 - - 1 Answers - 0 Comments A. Maria, A ratio will tell how one number is related to another number. A ratio may be written as A:B or A/B or by the phrase "A to B", where A = numerator and B = denominator. Sample: 3 dogs to 2 kids can be written: 3:2 or 3/2 or 3 to 2. Your question: one plastic to another can be written this way: .003cm: .004cm or this way: .003cm/.004cm or this way: .003cm to .004cm You need to divide the numerator by the denominator. .003cm = numerator .004cm = denominator Can you take it from here?
