Why average of ratios differs from average ratio of a series of numbers?
This is because the average of the ratios does not take account of the sizes of the numbers in the ratios.
Is a ratio a comparison between two ratios?
A ratio is a comparison between two values. The values can be integers or fractions (ratios).
How to create equivalent ratios?
Ratios are used to compare numbers. When you're working with ratios, it's sometimes easier to work with an equivalent ratio.
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
What is the relationship between two ratios with a constant rate or ratio?
The answer is "proprtional".

Is a ratio a comparison between two ratios?
A ratio is a comparison between two values. The values can be integers or fractions (ratios).
What is the difference between ratio and rational numbers?
Rational numbers are equivalent to ratios of two integers (the denominator being non-zero). A ratio is a relationship between two set of values. For example, the ratio of the circumference of a circle to its diameter is pi, which is not a rational number.
What is the relationship between radius ratio and coordination number in crystal packing?
The radius ratio influences the coordination number in crystal packing. Smaller radius ratios typically lead to higher coordination numbers due to more efficient packing of atoms. Larger radius ratios are associated with lower coordination numbers and larger interstitial spaces within the crystal lattice.
What are the ratios of 842?
The ratios of a number describe the relationship between that number and others. For 842, its ratios can be expressed in the form of fractions or comparisons with other numbers. For example, the ratio of 842 to itself is 1:1, while the ratio of 842 to 421 is 2:1. Other ratios can be created by comparing 842 to different numbers, such as 842:100 or 842:1000, depending on the context.
How are ratios and percent-ages related?
Given a ratio, a percentage is the numerator of an equivalent ratio whose denominator is 100.
How to create equivalent ratios?
Ratios are used to compare numbers. When you're working with ratios, it's sometimes easier to work with an equivalent ratio.
Can irrational numbers be defined as numbers that are not ratios?
Yes - except that you need to specify ratios of INTEGERS. pi/2 is a ratio of pi and 2 but it is irrational.
What is the difference between equal ratios and equivalent ratios?
To write equal ratios multiply both terms by the same number or divided both terms. For example, 2/ 9 is a ratio equal ratio will be 4/18. There is no difference between equal ratios and equivalent ratios.
How are ratios and rates related?
Rates are ratios that are renamed so that one of the numbers is 1. It is usually the denominator of the original ratio.
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 are ratios and percent ages related?
Given a ratio, a percentage is the numerator of an equivalent ratio whose denominator is 100.
