What is the relationship between edge length ratios area ratios and volume ratios of similar figures with various scale factors?
Area ratio = (edge-length ratio)2 Volume ratio = (edge-length ratio)3 Volume ratio = (area ratio)3/2
How to do scale models and maps?
The scale on a map or blueprint is a ratio. Ingredients sometimes need to be mixed using ratios such as the ratio of water to cement mix when making cement.
What is an equation that shows that two ratios or rates are equivalent?
scale factor
What is a number used to multiply by a ratio to give an equivalent ratio?
A number used to multiply by a ratio to produce an equivalent ratio is called the "scale factor." By multiplying each part of the ratio by the same scale factor, you maintain the proportional relationship while changing the values. For example, if you have the ratio 2:3 and multiply it by a scale factor of 2, the equivalent ratio becomes 4:6.
What is another name for a ratio scale?
Another name for a ratio scale is a "quantitative scale." It is characterized by having a true zero point, allowing for the comparison of both differences and ratios between values. Examples include measurements like height, weight, and temperature in Kelvin.
How you would scale up the ratio 10 boys to 14 girls to find equivalent ratios?
by multpulying 10 to 14 by 2
Is it true that the first numbers in the 2 equivalent ratios will always have a common factor?
Yes, it is true that the first numbers in two equivalent ratios will always have a common factor. This common factor is known as the scale factor, which is used to create equivalent ratios by multiplying or dividing both parts of the ratio by the same number. This ensures that the ratios maintain the same proportionality.

What ratio is equivalent to 8 to 9?
To find a ratio equivalent to 8 to 9, we need to find a common multiplier to scale both numbers. In this case, we can multiply both 8 and 9 by 2 to get 16 to 18, which is equivalent to 8 to 9. Therefore, the ratio equivalent to 8 to 9 is 16 to 18.
How would you scale down 10 boys to 14 girls to find the equivilent ratios?
You have to divide 10 and 14 by the same number to get your ratio. Example: 10 divided by 2= 5 & 14 divided by 2=7 so your ratio would be 5/7 or 5 to 7

Are multiple choice tests based on a ratio scale?
Multiple choice tests are not based on a ratio scale; they are typically considered nominal or ordinal scales. The responses represent categories (nominal) or ranked preferences (ordinal), but do not provide meaningful intervals or a true zero point, which are essential characteristics of a ratio scale. In a ratio scale, both differences and ratios between values have significance, which is not applicable to multiple choice answers.
How are maps and scale drawings related to ratios and proportions?
You need ratios to find out what scale to use.
How are ratios and scale factors different?
Ratios show the information of the side lengths scale factors show the information of how they are related
