Any two ratios, provided the second is not 0, form a proportion.
Let's form the proportion: 0.6/1.1 = n/8.47 or (6/10)/(11/10) = (n/1)/(847/100) (6/10)(10/11) = (n/1)(100/847) 6/11 = 100n/847 Proportion is a statement that two ratios are equal. The value of n makes this proportion true. The numbers that form a proportion are called the term of proportion. There is a special relationship between the terms, called the cross products property. That is, 6/11 = 100n/847 (6)(847) = (11)(100n) 5082 = 1100n so, n must be a number that when multiply 1100 equals 5082. 5082/1100 = (1100/1100)n 4.62 = n So, the proportion is: 6/11 = [100(4.62)]/847 6/11 = 462/847 Or, If you look at 847, you see that 11 x 77 = 847. So 100n must equals 6 x 77 = 462, in order to make the proportion true. So, 100n = 462 n = 4.62 and 100 x 4.62 = 462. Thus the proportion is: 6/11 = 462/847 If you want the original proportion is, 0.6/1.1 = 4.62/8.47
Substitute that value in the equation, and then check to see if the resulting statement is TRUE.
Technically the mean is more accurate, but it is not always a true representation, when you have a number that is way out of proportion with the rest of the numbers. That is when the median is more useful. See the related question below.

A true proportion is when two ratios are equal to one another. To prove this, you need to find the cross products of the ratios and see if they are equal. An example of a true proportion are the ratios 1/2 and 5/10, if you take the cross product the result is 2 x 5 = 1 x 10, which are equal.
set up a proportion and see if both sides simplify to the same answer. If the 2 ratios represent a constant ratio they will simplify into fractions
Answer: You check to see if fraction written in simplest form if you can't divide it by the Greatest Common Factor anymore.
Multiply the cross products, and see if they are equal. If they are equal, the proportion is true. If they are unequal, the proportion is false.
You can use ratios of adjacent sides to prove if two rectangles are similar by comparing to see if the ratios are the same
Let's form the proportion: 0.6/1.1 = n/8.47 or (6/10)/(11/10) = (n/1)/(847/100) (6/10)(10/11) = (n/1)(100/847) 6/11 = 100n/847 Proportion is a statement that two ratios are equal. The value of n makes this proportion true. The numbers that form a proportion are called the term of proportion. There is a special relationship between the terms, called the cross products property. That is, 6/11 = 100n/847 (6)(847) = (11)(100n) 5082 = 1100n so, n must be a number that when multiply 1100 equals 5082. 5082/1100 = (1100/1100)n 4.62 = n So, the proportion is: 6/11 = [100(4.62)]/847 6/11 = 462/847 Or, If you look at 847, you see that 11 x 77 = 847. So 100n must equals 6 x 77 = 462, in order to make the proportion true. So, 100n = 462 n = 4.62 and 100 x 4.62 = 462. Thus the proportion is: 6/11 = 462/847 If you want the original proportion is, 0.6/1.1 = 4.62/8.47
A ratio cannot become a proportion but can be solved in one. So you want to know how to tell if two ratios/fractions are equal? First, cross multiply the fractions, then check to see if the equation is true: 3/4 = 27/36 because 3 * 36 = 4 * 27 Work it out on your calculator. Also: 1/3 =/= 1/2 (does not equal) because 1 * 2 =/= 1 * 3 Another example: 1 / 2 = 2 / 4 because 1 * 4 = 2 * 2 Get it?
