Ratios and Proportions

We use ratios to compare two things. When we use words to express ratios, we use the word "to" - say "ratio to something else". Ratios can be written in several different ways. Use "to" or "colon" as the score.

Let's learn the details of ratio by using this figure. How do you write the ratio to a square circle, that is, a ratio of 3 to 6? The most common way to write ratios is the score, which is 3/6. You can also write "3" using the word "to". Finally, you can write this ratio by adding a colon 3: 6 between the two numbers. Please understand that these are all ways to write the same numbers

There are other ways to do the same comparison by using equal ratios. To find equal ratios, multiply or divide each item of the ratio by the same number (but not zero). For example, dividing the two items by the number of 3 with a ratio of 3: 6 gives an equal ratio of 1: 2. Do you think that these ratios represent the same comparison? Several other equal ratios are listed below. To determine if the two ratios are equal it is possible to divide the first number of each ratio by the second number. If the quotients are equal, the ratios are equal. Is the ratio of 3:12 equal to the ratio of 36:72? By dividing 2 you can see that the quotients are not equal. Therefore, the two ratios are not equal

You can also compare two quantities using decimal points and percentages. In the example from a box to a circle, the number of squares is "5/10", which means 50% of the number of circles.

This is a graph showing the number of free throws per 100 basketball players of 100 shots. Each comparison with the subject matter is expressed as a ratio, a decimal number, and a percentage. They are all equivalent, which means they are all different. Which would you like to use?

"Adjust" the ratio using 2 multiplication or division. A common type of problem with ratios involves using ratios to scale up or down two numbers. The ratio of all items that multiplies or divides a ratio by the same numerical value is the same as the original scale. Therefore, to scale the ratio, multiply or divide by the scale factor.

Ratios are around us, just comparing the two numbers each day (eg red fondant vs. Yellow Fondant). Scale is a statement that allows you to find unknown ratios from known ratios. With known ratios, I know these two numbers. With an unknown proportion, you only know one of the numbers. To solve the unknown, set the known ratio on one side and the ratio of unknown ratio on the other side, cross multiplication and solve the obtained equation. This method is always valid as long as it properly identifies known ratios and unknown ratios.

A number is a representation of amplitude. They are easier to compare, but the ratios of numbers are basically the same as quantities, as the ratio is usually similarity between ratios. Therefore, as a specific case, a certain percentage of the numerical value is included in the absolute value ratio.

Greek mathematician Euclid came up with a mathematical proportion of how to find a line and it led to the discovery of the Golden Ratio, also known as Phi. This ratio is when the ratio of the larger part to the smaller part equals the ratio of the larger part to the whole line. This is considered "perfect", hence it is called "golden ratio". Ionic order is one of three sequences of classical architecture, others are Doric and Corinth. That column is best known. Each column consists of base, shaft and upper spiral. In an ion sequence, a spiral has a shape like a reel or spiral. There is a load-bearing part of the stone horizontal on the pillar
