FACTS AND FORMULAE FOR RATIO AND PROPORTION QUESTIONS. 1. RATIO: The ratio of two quantities a and b in the same units, is the fraction a/b and we write it as a:b. In the ratio a:b, we call a as the first term or antecedent and b, the second term or consequent. Ex. The ratio 5: 9 represents 5/9 with antecedent = 5, consequent = 9.

A proportion on the other hand is an equation that says that two ratios are equivalent. For instance if one package of cookie mix results in 20 cookies than that would be the same as to say that two packages will result in 40 cookies. $$\frac{20}{1}=\frac{40}{2}$$ A proportion is read as "x is to y as z is to w".

Ratios and Proportions Workbook covers the Ratio of the ratio of two quantities. From this concept, we develop the related concepts of a rate (so much of one thing per so much of another thing) and a proportion (an equation of ratios).2/5(1).

Rates; Unit Rates; Exercises; Answers; We use ratios to compare two numeric quantities or quantities with the same units. Ratio. A ratio is the quotient of two numerical quantities or two quantities with the same physical units. For example, ancient Greek geometers believed that Ratio most pleasing rectangle to the eye had length and width such that the ratio of length to width was a specific.

In practice, a ratio is most useful when used to set up a proportion — that is, an equation involving two ratios. Typically, a proportion looks like a word equation, as follows: For example, suppose you know that both you and your friend Andrew brought the same proportion of scarves to caps.

Ratios can be written in three ways: 2 to 5 2 5 rate–A special ratio that compares two quantities measured in different types of units. Example: The water dripped at a rate of 2 liters every 3 hours → 2 L 3 hours unit rate–a rate with a and proportion book of 1.

Example: Shelby drove 70 mph. → 70 miles 1 hour. units. Just as ratios are rate to lowest terms, so are rates. The rate of can be written in simplest form as by reducing the fraction. By performing the division, we get what is called a unit rate.

In this example since We can describe the same rate as a unit rate of miles per gallon. Copyright. Price. Core Focus on Math:Stage 1 Mathematics Set. $ The ratio is 2 to 5 or or 2/5. All these describe the ratio in different forms of fractions.

The ratio can consequently be expressed as fractions or as a decimal. in decimals is A rate is a little bit different than the ratio, it is a special ratio. It is a comparison of measurements that have different units, like cents and grams. The grocery store is a good source of ratios in real life.

While looking at the prices of various groceries, you can easily illustrate ratios using two different boxes of cereal. For example, if a ounce box of cereal costs $3 and a ounce box of cereal costs $5, the 20 ounce box is the better value because each ounce of cereal is cheaper.

Ratios, rates, and percentages are some of the most useful math concepts in real life (and what is REAL life anyway, huh?). From baking recipes to sports, these concepts wiggle their way.

The ratio of frogs to tadpoles in a pond is After scooping up some frogs and tadpoles in a jar, our ratio of frogs to tadpoles is Is the ratio of amphibians in our jar proportional to the ratio of amphibians in the entire pond.

We first write a ratio for the amphibians in the pond and then one for the amphibians in our jar. Pond ratio. A ratio is a mathematical comparison of two numbers, based on division.

For example, suppose you bring 3 shirts and 5 ties with you on a business trip. Here are a few ways to express the ratio of shirts to ties: 3 to 5 3/5 A good way to work with a ratio is to turn [ ].

The concept of ratio defines us to compare two quantities while the proportion is an equation which shows that two ratios are equivalent. Hence, it is easy to calculate the ratio of the given proportion. Ratio, rate and proportion (EMGT) What is a ratio.

(EMGV) A ratio is a comparison of two or more numbers that are usually of the same type or measurement. If the numbers have different units, it is important to convert the units to be the same before doing any calculations.

We write the numbers in a ratio with a colon (:) between them. Pythagoras and the Ratios: A Math Adventure (Charlesbridge Math Adventures) by Julie Ellis and Phyllis Hornung Peacock | Feb 1, out of 5 stars Ratio and Proportion Real life applications of ratio and proportion are numerous.

The concept occurs in many places in mathematics. When you prepare recipes, paint your house, or repair gears in a large machine or in a car transmission, you use ratios and proportions.
