How do you solve a proportion if a variable is missing?
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

How do you work out proportions?
to solve a proportion you have to set up a problem Ike this...24/65 = 12/x you fill in the missing variable with a letter.most common is x.the missing variable is the variable you are trying to solve for.now you do 24x/24 = 780/24 you do 24x and put 24 under it.now do 65 times 12which is 780.so you put 780 as the other fraction.now do 780 divided by 24 which is 325.so 325 is325 is the answer.That's how you solve proportions.
How do you solve proportions using cross products?
say it is 1 over 2 is equal to x over 4 you multiply 4 and 1 then 2 and x and you get 4=2x. Solve for x = 2. So the equivalent proportion is 2/4.
