Below are a few examples of authentic ratios to practice calculating. Use the following demographic information about a marching band to complete the following exercises using ratios comparing two or more quantities.
Instrument type. What is the ratio of boys to girls? What is the ratio of freshmen to the total number of band members? What is the ratio of percussion to woodwinds to brass? What is the ratio of freshmen to seniors to sophomores? Note: is a prime number and cannot be reduced in this ratio. If 25 students left the woodwind section to join the percussion section, what would be the ratio for the number of woodwind players to percussion?
The ratio of the number of players in woodwinds to percussion is Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile. Measure ad performance. Select basic ads.

A ratio table is a list containing the equivalent ratios of any given ratio in a structured manner. The following ratio table gives the relation between the ratio and four of its equivalent ratios. The equivalent ratios are related to each other by the multiplication of a number.
Equivalent ratios are obtained by multiplying or dividing the two terms of a ratio by the same number. In the example shown in the figure, let us take the ratio and find four equivalent ratios, by multiplying both the terms of the ratio by 2, 3, 6, and 9. As a result, we get , , , and Example 1: There are 49 boys and 28 girls in school. Express the ratio of the number of boys to that of girls.
The GCF of 49 and 28 is 7. Now, to simplify, divide the two terms by their GCF which is 7. Example 2: A music class has 30 students. Out of the 10 of them were adults and the rest were children. What is the ratio of the number of children to the total number of students in the music class? The GCF of 87 and 75 is 3. We divide each term in the ratio by 3. Thus, the ratio in the simplest form is Ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one.
For example, if the number of marks scored in a test is 7 out of 10, then the ratio of marks obtained to the total number of marks is written as A ratio can be written by separating the two quantities using a colon : or it can be written in the fractional form. What this means is that for every one unit of height on the left bar, the tall bar has four height units.
Hence "four to one". Using the bar example again, we ca also write the ratio as a fraction, where the top numerator is one height, and the bottom denominator is the other.
We can pick either one to be the top, so using the smaller one, we can write: which reduces to. This fraction can then also be written as a decimal.
