To set up a proportion problem for a missing value, first identify the two ratios that are being compared. Write them as a fraction, equating the two ratios (e.g., ( \frac{a}{b} = \frac{c}{d} )). If one value is missing, use a variable (like ( x )) to represent it. Then, cross-multiply to solve for the missing value, and simplify the equation to find ( x ).
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
Yes.
An inverse proportion between two variables is when the value of one variable increases, the other decreases. Mathematically, this is shown as: x = k / yn where x and y are the two variables, and k and n are constants.
When you have two numbers in a proportion, you can use cross-multiplication to find the unknown value or confirm the relationship. Set up the proportion as a fraction (a/b = c/d) and cross-multiply to get ad = bc. If you're solving for a missing number, isolate that variable and solve the equation. Lastly, ensure the proportion remains valid by checking if the ratios are equal.

There cannot be a "proportion of something": proportion is a relationship between two things, and how you solve it depends on whether they (or their transformations) are in direct proportion or inverse proportion.

Yes.
Are in direct proportion
It is a direct proportion.
An inverse proportion between two variables is when the value of one variable increases, the other decreases. Mathematically, this is shown as: x = k / yn where x and y are the two variables, and k and n are constants.

You need two independent linear equations to solve for two unknown variables.
You can look at the ratio that is given to you for example in geometry... It is used to compare two ratios or make equivalent fractions. Use the ratio and make that the denominator of the proportion and cross multiply.A proportion will help you solve problems like the one below. Jane has a box of apples and oranges in the ratio of 2:3. If she has six apples, how many oranges does she have?Before we begin to set up proportions for a word problem, we will concentrate on solving proportions. Remember, a proportion is a comparison between two ratios. The proportion shown below compares two ratios which are in the fraction form. 1 x - = - 2 6
The other variable is doubled
inversely proportional or inverse proportion
