### Example Question #31 : How To Divide Fractions

The above parallelogram has been divided into triangles of equal size and shape. The total area of the shaded region is 2,400. Calculate the area of the entire parallelogram.

**Possible Answers:**

**Correct answer:**

20 of 24 triangles have been shaded in; this is of the parallelogram. I we let stand for the total area of the parallelogram, then is equal to the shaded area, or 2,400, so we solve:

### Example Question #31 : How To Divide Fractions

Solve the following:

**Possible Answers:**

**Correct answer:**

When dividing fractions, we will leave the first fraction as it is. We will then take the reciprocal of the second fraction. The reciprocal of a fraction is when the numerator becomes the denominator and the denominator becomes the numerator. In other words, we flip the fraction. Once we find the reciprocal, we will then multiply the fractions together. That's right, we will NOT actually be dividing any numbers.

So,

we must take leave the first fraction alone. For the second fraction, we will take the reciprocal. We must first write the number in fraction form. We get

Now, we will take the reciprocal and multiply.

We will multiply straight across.

### Example Question #552 : Numbers And Operations

Divide the following:

**Possible Answers:**

**Correct answer:**

To divide fractions, we will follow these steps:

- Leave the first fraction alone.
- Change the division sign to a multiplication sign.
- Write the reciprocal of the second fraction (i.e. the numerator becomes the denominator and the denominator becomes the numerator).
- Multiply.

So to solve,

we will follow the steps.

- Leave the first fraction alone.

- Change the division sign to a multiplication sign.

- Write the reciprocal of the second fraction.

- Multiply

### Example Question #31 : How To Divide Fractions

Divide the following:

**Possible Answers:**

**Correct answer:**

To divide fractions, we will use the following steps:

- Leave the first fraction alone
- Change the division sign to a multiplication sign.
- Write the reciprocal of the second fraction.a
- Multiply.

So, let's follow the steps.

1. Leave the first fraction alone. So, we get

2. Change the division sign to a multiplication sign.

3. Write the reciprocal of the second fraction. To do this, we will move the numerator to the denominator, and move the denominator to the numerator. In other words, we will flip the fraction.

4. Multiply. We will multiply straight across.

### Example Question #405 : Fractions

Solve the following:

**Possible Answers:**

**Correct answer:**

To divide, we will follow these steps:

- Write any whole number as a fraction.
- Keep the first fraction as is.
- Change the division sign to a multiplication sign.
- Replace the second fraction with it's reciprocal.
- Multiply.

Now, we will follow those steps for the problem

- We will write all whole numbers as fractions. So the number 6 can be written as a fraction. We know that any whole number can be written over 1. So,

- Now, we will keep the first fraction the way it is. We get

- Now, we will change the division sign to a multiplication sign. We get

- Now, we will replace the second fraction with it's reciprocal. To do that, the numerator will become the denominator, and the denominator will become the numerator. In other words, we will flip the fraction. We get

- Now, we will multiply straight across. We get

Therefore,

### Example Question #32 : How To Divide Fractions

Divide the following:

**Possible Answers:**

**Correct answer:**

To divide fractions, use the following steps:

- Leave the first fraction alone.
- Change the division sign to a multiplication sign.
- Replace the second fraction with it's reciprocal.
- Multiply.

So, given the problem

we will follow the steps.

- Leave the first fraction alone.

- Change the division sign to a multiplication sign.

- Replace the second fraction with it's reciprocal. To write the reciprocal of a fraction, the numerator will become the denominator, and the denominator will become the numerator. In other words, we will flip the fraction.

- Multiply. To multiply, we will multiply straight across. We get

### Example Question #551 : Numbers And Operations

Divide the following:

**Possible Answers:**

**Correct answer:**

To divide fractions, follow these steps:

- Leave the first fraction alone.
- Change the division sign to a multiplication sign.
- Replace the second fraction with it's reciprocal.
- Multiply.

So, given the problem

we will follow the steps.

- Leave the first fraction alone. In this case, we need to write 10 as a fraction. We know that whole numbers can be written as fractions over 1. So, we get

- Change the division sign to a multiplication sign.

- Replace the second fraction with it's reciprocal. To write the reciprocal, the numerator becomes the denominator, and the denominator becomes the numerator. In other words, we will flip the second fraction.

- Multiply. We will multiply straight across.
