Students learn to find equal ratios by first writing the given ratio as a fraction, then multiplying the numerator and denominator of the fraction by the same number. For example, to find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7. Next, multiply both the numerator and denominator of 1/7 by 2, to get 2/14, or 2:14, and multiply the numerator and denominator of 1/7 by 3, to get 3/21, or 3:21. So 2:14 and 3:21 are two ratios that are equal to 1:7. Students are also asked to determine whether two given ratios are equal, by first writing each ratio as a fraction, then writing each fraction in lowest terms. If the two fractions are the same when written in lowest terms, then the ratios are equal.
A ratio is a comparison of two numbers. You can write a ratio in these ways: a to b, a : b, or a/b. Ratios are often written as fractions. A ratio that is expressed as a fraction is generally written in lowest terms. If the ratio involves unit of measure, you must ensure that the units are the same. Example: Write ratios in lowest terms. 20/52 = (20/4)/(52/4) = 5/13 240/200 = (240/40)/(200/40) = 6/5 There are continued ratio, or extended ratio, which relates more than two numbers. Example: The measures of the angles of a triangle are related by the ratio 3 : 4 : 5. Find the measure of each angle. Solution: The ratio 3 : 4 : 5 is equivalent to 3x + 4x + 5x. We write an equation by using, 3x, 4x, and 5x to represent the measures of the angles. The sum of the angles of a triangle is 180 degrees. So, 3x + 4x + 5x = 180 12x = 180 x = 15 Thus, the measures of the angles are 45 degrees, 60 degrees, and 75 degrees.

Ratios that are equal to each other can be 3/4=75/100 or 1/4=25/100
The ratios of areas are the squares of the ratio of lengths (and the ratio of volumes are cubes of the ratio of lengths). As the perimeter of the second is twice the perimeter of the first, each length of the second is twice the length of the first, and so the ratio of the lengths is 1:2 Thus the ratio of the areas is 1²:2² = 1:4. Therefore the surface area of the larger prism is four times that of the smaller prism.
3:1, 6:2, 9:3
To use ratio tables for comparing ratios, first, create a table that lists the values of each ratio in corresponding rows. For example, if you're comparing the ratios of apples to oranges and bananas to grapes, list the quantities of each in separate columns. By filling in the table with equivalent values (e.g., scaling each ratio to a common denominator), you can easily see which ratio is greater or if they are equivalent. This visual representation helps clarify the relationships between the ratios at a glance.
A ratio is 531054006300:1. To obtain equivalent ratios simply multiply each of these numbers by any non-zero number.
To use equivalent ratios to complete a table, first identify the ratio you want to work with. Then, multiply or divide both terms of the ratio by the same number to find equivalent values. For example, if the ratio is 2:3, you can find equivalent ratios like 4:6 (by multiplying both terms by 2) or 6:9 (by multiplying by 3). Fill in the table with these calculated ratios to maintain consistency throughout.
similarity ratios are ratios in which both the ratios are equal to each other
No; each ratio has to be the same for a direct variation.
To determine which set of ratios are equivalent, we can simplify each pair of numbers. The ratio of 36 to 918 simplifies to 1:25.5, while 47 to 48 simplifies to approximately 0.979. The ratio of 12 to 34 is approximately 0.353, and 216 to 116 simplifies to approximately 1.862. None of the ratios are equivalent to each other.
A ratio table is used to organize pairs of equivalent ratios, making it easier to visualize their relationships. By listing the ratios in a structured format, one can identify corresponding values that maintain the same proportional relationship. Once the ratios are established, they can be plotted on a coordinate plane, where each pair represents a point. This graphical representation helps to illustrate the linear nature of equivalent ratios and can reveal trends or patterns in the data.
Multiply each part of the ratio by the same number.
Three equivalent ratios of 1 to 3 are 2 to 6, 4 to 12, and 5 to 15. These ratios maintain the same proportional relationship, meaning that for every 1 unit of the first quantity, there are 3 units of the second quantity. Each ratio can be derived by multiplying both parts of the original ratio by the same number.
No but the equal ratios are called Equivalent Ratios.
Three equivalent ratios to 18 to 6 are 36 to 12, 54 to 18, and 72 to 24. These ratios can be found by multiplying both terms of the original ratio by the same number, such as 2, 3, or 4. Each of these pairs maintains the same relationship as the original ratio of 3:1.
