Example Question #393 : Fractions
Divide.
Multiply the first fraction by the reciprocal of the second fraction.
Example Question #24 : How To Divide Fractions
Simplify the following expression:
Simplify the following expression:
To divide fractions, we must multiply by the reciprocal.
That means that we should first flip our second fraction. (This is called taking the reciprocal
Next, we can simplify by dividing the smaller numbers on the left out of the bigger numbers on the right.
So our answer is:
Example Question #541 : Numbers And Operations
Simplify the following expression:
Simplify the following expression:
To divide fractions, we need to multiply by the reciprocal. This means that we flip the second fraction and then multiply:
Before multiplying, simplify the two fractions by factoring out a seven from the 42 and the 35. We can do this, because they are on opposite sides of the fraction.
So we get an answer of:
Example Question #32 : How To Divide Fractions
Simplify the following:
To divide fractions, we will take the first fraction and multiply it by the reciprocal of the second fraction.
(Reciprocal simply means we will take the fraction and flip it. The numerator will become the denominator and the denominator will become the numerator.)
So,
will become
Now, we multiply.
Now, we can simplify. We can divide the numerator and the denominator by 3. We get
Example Question #33 : How To Divide Fractions
The reciprocal of is . What is the reciprocal of ?
The reciprocal of is , so is the reciprocal of , or
The reciprocal of this is 3.
Example Question #34 : How To Divide Fractions
Divide the following:
To divide fractions, we will simply turn it into multiplication. We will leave the first fraction alone. We will take the second fraction, and write the reciprocal. Then, we will multiply the two fractions together. We have
we will leave alone. We will take and write the reciprocal (flip the fraction, the numerator and denominator switch places). The reciprocal is . Now, we multiply.
Example Question #1432 : Isee Middle Level (Grades 7 8) Mathematics Achievement
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.
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 #401 : Fractions
Solve the following:
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 #401 : Fractions
Divide the following:
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 #402 : Fractions
Divide the following:
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.
