Rewrite both the numerator and denominator using factors of two.

Reduce this fraction.

The number 99 goes into 23 four times, since , and will have a remainder of seven.

The answer is:  

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

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.

In order to solve for , we'll need to move all of the variables on its side to the other side of the equation.

We can see that  is currently the denominator to , so we need to move the  in order to solve for .

To move the , we'll have to divide it on the other side. Keep in mind though that the  is in the numerator, so it will stay in the numerator when it divides over.

We cannot proceed with the question as there is nothing left to do. Our variables are different and the  can stay where it is.

Our answer is 

In order to solve for , we need to move all the numbers and variables to the other side of the equation.

We can see that  is currently being multiplied by . In order to move the , we need to divide it on the other side of the equation.

Both  and  can be divided by , which in turn gets rid of the  in the denominator. 

We cannot proceed any farther since there is nothing left to do in the equation.

Our answer is 

In order to solve for , we'll need to move all the other variables to the other side of the equation. Currently  is stuck to , so we need to move the  to the other side.

In order to move , we'll have to divide it to the other side of the equation.

Since all the variables are different, we cannot do anything else to simplify this equation.

Our answer is 

Division is another way of seeing how many of the number we are dividing with is in the number we are dividing. 

Let's take a look at . This is the number we are dividing, and  is the number we are dividing with as told by their placement. We want to see how many 's there are in .

To figure this out, we'll add a  each time until we get to .

We have now reached , so how many 's did it take us to get there? It took us  's to get to , and if you check with a calculator you will see that this is the answer as well.

Our answer is .

When a negative number is multipied by a positive number, the result is negative.

Therefore,

.
