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 the ratios of a length on a scale drawing to the corresponding length on the real object?
The scale factor.
How Do you Find a ratio?
A ratio is expressed as the relationship of whole numbers or decimals. The numbers can determine percentages, scales, parts of a solution, or output per input in gears. The ratio is simply a multiple and can be changed to other ratios just as fractions are changed, by multiplication of both sides.Some examples of ratios are:If you need to mix 1 part whitewash with 2 parts water, the ratio is 2:1If a gearbox input shaft makes 1 revolution causing the output to make 2.6 revolutions, the ratio is 1:2.6If a drawing of a house is drawn on paper, it is drawn much smaller but to scale with the real house dimensions. If the drawing is 120 times smaller than the house, then the scale is 1:120If 26 out of every 100 adults smoke cigarettes, then the ratio is 26:100In the final two examples, you can express the ratio scale as a fraction (1/120th scale) and the percentage of smokers as 26% (26 percent).To simplify a ratio, divide both sides by the smaller number. E.g. the ratio of 300 to 10 (300:10) is 30 to 1, and the ratio of 10:20 equals the ratio 1:2 (1/2).
How you would scale up the ratio 10 boys to 14 girls to find equivalent ratios?
by multpulying 10 to 14 by 2

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
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
What is a representative scale?
A representative scale refers to the ratio of a distance on a map to the corresponding distance on the Earth's surface. It helps users understand the relationship between distances on a map and in reality. It is often depicted as a scale bar or ratio.
Is age an interval or ratio scale of measurement?
It is a ratio scale of measurement.
Are the ratios of all three pairs of corresponding sides of similar triangles equal?
Yes. When a shape is enlarged the scale factor gives the ratio between corresponding lengths of the enlargement and the original.
What is the ratios of a length on a scale drawing to the corresponding length on the real object?
The scale factor.
How do ratios and fractions relate to scale?
They both can be divided.
