Lesson 2: Multiplying fractions and whole numbers

# Multiplying unit fractions and whole numbers

Learn how to multiply a whole number by a fraction, using both visual and computational methods. Multiplying 1/2 by 5 can be understood as adding five 1/2's together, resulting in 5/2. Created by Sal Khan.

• If 1/2 x 5 is 5/2 does that mean 5 x 1/2 is the same?
• Yes. When you multiply a fraction or whole number, if the places are interchange, the answers are the same!
#Warning:This doesn't mean the application process is the same!!XD
• 5/6 × 4 is what
• The answer is 20/6, but it is not simplified. You should always simplify fractions if you can. 20/6 can be simplified to 10/3. since 10/3 is an improper fraction, we need to change it to a mixed number. 10 goes inside 3, 3 times and there is one left over. So the answer is 3 1/3. Sorry if this doesn't make sense, I'm only in fifth grade.
• The star (*) is just another way of saying your multiplying so x is also * just with a different shape. =)
• Who else likes burgers?
• i like burgers
• how would you multiply 3 1/4 x 6?
• Try converting 3 1/4 to an improper fraction, that should make it a lot easier
• What does it mean by find each product
• This could mean that there's more than 1 multiplication problem present in the question. Which, in this case, you have to find the products of the multiplication given. I hope this helps Eva Medina Whitley!
• how do you do mixed fractions * fractions
• For example ,if they ask you (5 1/2) right?than you just calculate it like this(2 times five,which is 10 ,after that,youplus 1 to 10.)I hope it will help ALIVIA S.
