Lesson 8: Dividing fractions

# Dividing fractions: 2/5 ÷ 7/3

Dividing fractions is a breeze when you follow these simple steps! First, multiply the first fraction by the reciprocal of the second fraction. Then, multiply the numerators and denominators separately. Voila! You've successfully divided two fractions and found your answer. Keep practicing to master this essential math skill.

• is there another method to do this
• (Prepare for a long answer) Srivish, To answer your question, there IS another way to solve it. Cross multiplication. Here are some steps to help solve it
1: First take your Equation, and if you've already written an answer. Erase it, then write a new set of brackets to have your fractions in.
2: Secondly, take your equation. Let's ignore that division sign for now. So you have your two pairs of fractions, Correct?
3: TO do this, you will have to multiply a bit. First, take the numerator of your first fraction, and multiply it with the denominator of the second Fraction. This will turn into your new Numerator. Now cross off the fractions you just used.

However, if your Equation with variables, such as X, the whole question will change. In order to adapt to this, you will have to change the way you solve it. Here is a link detailing how to.

• at 0.29 i didn't understand why we flipped it
• Because dividing is the same thing as multiplying by the reciprocal of a number. A reciprocal is basically just a number flipped upside down. Example: 4 ÷ 2 is the same thing as 4 * 1/2.
• This is really tricky. As a 5th grader I should be knowing this stuff, (technically a 6th grader because I graduated last Friday.) And It's really hard for me to focus at this stuff, but to anyone out there, promise me you wont give up <3
• Practice makes perfect!! Good luck! ;)
• How the heck does a reciprocal even work?! I'm mind blown. Can somebody tell me why?
• A reciprocal is when you flip the numerator and the denominator to get it. So 2/4 would become 4/2, 5/6 would become 6/5, and so forth.
• Do you still have to do the extra math to the side to get the actual answer.
• not if you feel like torchuring yourself lol (no seriously, if you dont, it'll take forever to do it).
• When dividing two fractions how many methods are there and what are they?
• I think there is only one method, but it is shown or named in several ways. KCF (keep the first fraction, change the sign from / to *, and flip the second fraction) is a common mnemonic device to help remember what to do. The words are the same method of reciprocating the denominator and multiplying.
• I like and respect Khan Academy, but could they make the videos fast like this one? It gets boring when to rant.
