Dividing Fractions by Fractions - a Step-by-Step Guide

How do you handle remainders when dividing fractions?

Press to flip

When dividing fractions, remainders are not typically encountered since the division results in another fraction. However, if there is a remainder, it can be expressed as a mixed number or a fraction with a larger denominator.

How do you divide a fraction by another fraction?

Press to flip

To divide a fraction by another fraction, use the phrase 'keep, change, flip'. Keep the first fraction the same, change division to multiplication, and flip the second fraction.

What is the result of dividing 47/3 by 7?

Press to flip

The result of dividing 47/3 by 7 is 4/3.

What is the result of dividing 4/3 by 9/2?

Press to flip

The result of dividing 4/3 by 9/2 is 2/3.

What is the result of dividing 4/7 by 8/21?

Press to flip

The result of dividing 4/7 by 8/21 is 3/2.

How can you simplify the fraction 12/18?

Press to flip

You can simplify the fraction 12/18 by dividing both the numerator and the denominator by their greatest common divisor, which is 6. This gives you the fraction 2/3.

Why is it beneficial to cancel out numbers when multiplying fractions?

Press to flip

Canceling out numbers when multiplying fractions simplifies the calculation and makes it easier to find the answer.

What is the cancellation method in fraction division?

Press to flip

The cancellation method involves breaking down the numerator and denominator of the fractions into smaller factors and canceling out any common factors before multiplying.

How can you use the cancellation method to simplify 4/7 divided by 8/21?

Press to flip

You can simplify 4/7 divided by 8/21 by breaking down 21 into 7 * 3 and 8 into 4 * 2, then canceling out the common factors of 4 and 7, resulting in 3/2.

Why is it important to keep the first fraction the same when dividing fractions?

Press to flip

Keeping the first fraction the same ensures that you are dividing by the correct fraction and not altering the original problem.

What happens if you don't change division to multiplication when dividing fractions?

Press to flip

If you don't change division to multiplication, you will not be performing the correct operation and will not get the right answer.

How do you flip a fraction when dividing fractions?

Press to flip

Flipping a fraction means inverting it, so the numerator becomes the denominator and vice versa.

Can you always simplify a fraction after dividing two fractions?

Press to flip

Yes, after dividing two fractions, you can simplify the resulting fraction by finding and dividing by the greatest common divisor of the numerator and the denominator.

What is the purpose of the 'keep, change, flip' method in fraction division?

Press to flip

The 'keep, change, flip' method is a mnemonic device that helps you remember the steps to divide fractions correctly: keep the first fraction, change division to multiplication, and flip the second fraction.

How do you know when to apply the cancellation method in fraction division?

Press to flip

Apply the cancellation method when you can identify common factors between the numerators and denominators of the fractions being multiplied.

What is the final step after performing the 'keep, change, flip' method?

Press to flip

The final step after performing the 'keep, change, flip' method is to multiply the numerators and then multiply the denominators of the fractions.

Can you divide a fraction by a whole number using the 'keep, change, flip' method?

Press to flip

Yes, you can divide a fraction by a whole number by first converting the whole number to a fraction with a denominator of 1, then applying the 'keep, change, flip' method.

How do you simplify the fraction 84/126?

Press to flip

You can simplify the fraction 84/126 by dividing both the numerator and the denominator by their greatest common divisor, which is 42. This gives you the fraction 2/3.

What is the result of dividing 5/8 by 3/5?

Press to flip

The result of dividing 5/8 by 3/5 is 25/24.

Can you explain the process of dividing a fraction by a mixed number?

Press to flip

To divide a fraction by a mixed number, first convert the mixed number to an improper fraction, then apply the 'keep, change, flip' method to divide by the improper fraction.

How do you handle remainders when dividing fractions?

Press to flip

When dividing fractions, remainders are not typically encountered since the division results in another fraction. However, if there is a remainder, it can be expressed as a mixed number or a fraction with a larger denominator.

How do you divide a fraction by another fraction?
