Example Question #2 : Solving Linear Equations With Part, Percent, And Whole
If of an unknown number is , what is the unknown number?
First, we need to convert into a decimal.
Then, we can write the following equation using the information given in the question:
,
where is our unknown number.
Now, solve for
Example Question #1 : Solving Linear Equations With Part, Percent, And Whole
When an unknown number is increased by , it becomes the number . What is the unknown number?
First, convert the percent into a decimal.
Now, increasing an unknown number by can be written by the following expression:
Next, set that equal to 88, since that is what the question tells us to do.
Now solve.
Example Question #4 : Solving Linear Equations With Part, Percent, And Whole
of an unknown number is . What is the unknown number?
Before we can write an equation, we need to turn the percent into a decimal.
Now, we can write the following equation:
Divide both sides by .
Example Question #5 : Solving Linear Equations With Part, Percent, And Whole
If of an unknown number is , what is the unknown number?
First, let stand for the unknown number.
Then, let's convert the percentage into an equivalent decimal
Translating the question above into an equation, we have:
Dividing both sides by , we see that .
