Note: When I say number, I am also including variables and variables with a coefficient (terms).
You Have to Cross-Multiply, and then solve algebraically.
Lets say you have a problem like this: x/2=2/8
# Multiply the Top Left number with the Bottom Right number, and put it on one side of an = sign # Multiply the Bottom Left number with the Top Right number, and put it on the other side of the = sign.
In our case, multiply the inner numbers and put them on one side of an = sign, and then multiply the outer numbers and put them on the other side of the = sign.
In our case, you get: 2*2 = 8x
4 = 8x
4/8 = x
.5 = x
So there you have it, x=.5

How do you solve fractions with letters?
use proportions
How can you use proportions to solve equations with variables on both sides?
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
How do you solve for the variables?
Yes, that is what you are normally required to solve for.
How do you find the value of a variable of a proportional ratio?
Cross multiply then solve for the variable.
How do you know whether a relation is a function?
Use the definition of a function. If, for any value of one variable, there is only a single possible value of the second variable, then the second variable is a function of the first variable. The second variable is often called the "dependent variable". If you can solve an equation explicitly for the dependent variable, then it is a function. If you can NOT solve it for a variable, it may or may not be a function - it turns out that some equations are hard or impossible to solve explicitly for one of the variables.
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.
What cause the application of law of variable proportion?
Causes of law of variable proportions
Can you solve for a variable in an equation?
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
What is the difference between variable proportions and returns to scale?
what is relationship between change in input and output. In the return's to scale (long term concept) all the factor are variable but in the variable proportions are some factor variable and some factors are fixed.
How do you solve fractions with letters?
use proportions
A chemical combination of two or more substance in variable proportions is called?
A chemical combination of two or more substances in variable proportions is called a mixture. Mixtures can be either homogeneous (uniform composition throughout) or heterogeneous (non-uniform composition).
How can you use proportions to solve equations with variables on both sides?
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
Solve xyz for the variable y?
solve x=yz for the variable y
Why does the law of variable proportions operate?
conduction, convection, and radiation
How do you solve an or problem if a variable is unrestricted in sign?
Solve the problem using the + sign for the variable. Then solve the problem using the - sign for the variable. Report your answer as the answer that you got using + or the answer that you got using -.
What is the math term VEST?
variable equation solve it test it
How do you solve for the variables?
Yes, that is what you are normally required to solve for.
