Example Questions
Example Question #265 : Ged Math
Solve for 
In order to solve for 
Since all the variables are different we can't do anything else to simplify the equation.
Our answer is
Example Question #264 : Numbers And Operations
Solve for 
In order to solve for 
At the moment 
Let's begin by multiplying 
We still have 
Since there are no numbers and none of the variables are the same we can't do anything else to this equation.
Our answer is
Example Question #267 : Numbers And Operations
Solve this equation:
Multiplication is a lot like adding, just with multiples of the same number.
We can solve this two ways, so we will do it both. Let's start with 
So we can see that 
Now let's go with 
Either way you pick, both routes give us the answer 
Our answer is 
Example Question #101 : Basic Operations
Divide:
Use the long division process:
Example Question #102 : Basic Operations
Which of the following is an undefined expression?
Do not use a calculator.
Both differences are defined, as there is no restriction on what two numbers can be subtracted. Zero divided by any nonzero number yields a quotient of zero, so 
Example Question #271 : Ged Math
If 10,000 is divided by 23, what is the remainder?
Do not use a calculator.
Use the long division process.
The remainder is 18.
Example Question #103 : Basic Operations
Forty friends are renting a party bus to the school prom. Rental of the party bus will cost $280 up front plus $20 per hour. The friends have the bus from 5:00 PM to 2:00 AM.
The friends have agreed to split the cost evenly. How much will each pay?
From 5:00 PM to 2:00 AM will be
The bus will cost the students
which, divided evenly among 40 students, means that each will pay
Example Question #104 : Basic Operations
Divide and rewrite as a mixed fraction:
Rewrite both the numerator and denominator using factors of two.
Reduce this fraction.
The number 99 goes into 23 four times, since 
The answer is:
Example Question #5 : Division
Divide the following:
To divide fractions, we will take the first fraction and multiply it by the reciprocal of the second fraction. To find the reciprocal of a fraction, the numerator becomes the denominator, and the denominator becomes the numerator. In other words, we will flip the fraction. So, we get
Example Question #273 : Ged Math
Which number is not a factor of 66?
Divide 66 by each of the four choices. The division that yields a nonzero remainder reveals the number that is not a factor.
66 divided by 6, 11, or 22 yields a zero remainder; 66 divided by 12 yields a nonzero remainder. Therefore, 12 is the nonfactor.
