Example Question #21 : How To Solve One Step Equations With Fractions In Pre Algebra
Solve for .
To solve for , the first thing we need to do is isolate the variable. That means we want ONLY on the left side of the equation.
To divide by a fraction, we need to multiply by the reciprocal. The reciprocal of .
Example Question #22 : How To Solve One Step Equations With Fractions In Pre Algebra
Solve for if,
To solve for we must get all of the numbers on the other side of the equation as .
To do this in a problem where is being divided by a number, we must multiply both sides of the equation by the number.
Since it is a fraction we must multiply each side by the reciprocal like this
The numbers on the left cancel and we have
To multiply a fraction you multiply the top number of the first fraction by the top number of the second fraction and the bottom number of the first fraction by the bottom number of the second fraction.
We do this and find the answer is
Reduce the fraction to get

.
Example Question #24 : How To Solve One Step Equations With Fractions In Pre Algebra
Solve for if
To solve for we must get all of the numbers on the other side of the equation of .
To do this in a problem where is being divided by a number, we must multiply both sides of the equation by the number.
In this case the number is so we multiply each side of the equation by to make it look like this
The on the left side cancel and then we multiply
The answer is .
Example Question #25 : How To Solve One Step Equations With Fractions In Pre Algebra
Solve for .
To solve , we need to isolate . That means we want all the numbers on one side and the on the other side.
For this problem, that means we need to get rid of on the right side. To divide by a fraction, we multiply by the reciprocal.
Example Question #26 : How To Solve One Step Equations With Fractions In Pre Algebra
Solve for .
To solve, we need to isolate . Therefore, we want all the numbers on one side and the on the other side.
For this problem, we need to get rid of on the right side. To divide by a fraction, we multiply by the reciprocal.
Example Question #27 : How To Solve One Step Equations With Fractions In Pre Algebra
Solve for if .
To solve for we must get all of the constants on the other side of the equation as .
To do this in a problem where is being subtracted by a number, we must add the number to both sides of the equation.
In this case the number is so we add to each side of the equation:
To add fractions we must first ensure that we have the same denominator.
To do this we must find the least common multiple of the denominators.
In this case the LCM is .
We then multiply and to get the same denominator for both fractions.
To multiply a fraction, multiply the top number of the first fraction by the top number of the second fraction and the bottom number of the first fraction by the bottom number of the second fraction.
We then add the numerators together and place the result over the new denominator.
Example Question #28 : How To Solve One Step Equations With Fractions In Pre Algebra
Solve for .
Our goal here is to isolate . That means we want just on the left side.
For our problem, , we need to get rid of the fraction. Dividing by a fraction is the same as multiplying by the reciprocal.
Example Question #29 : How To Solve One Step Equations With Fractions In Pre Algebra
Solve for .
When solving for , we want to isolate it. That means we want only on the right side of the equation.
For our given equation, , we need to divide both sides by .
Dividing by a fraction is the same as multiplying by the reciprocal so this will look like:
