Lesson 3: Dividing unit fractions by whole numbers

Visually dividing unit fraction by a whole number

Learn how to divide fractions by whole numbers. You'll watch how dividing a fraction into smaller parts changes the denominator. Then, you'll practice this concept with examples to understand how dividing fractions works.

• i cant understand the topic
• To divide a unit fraction by a whole number:

1) Write 1 in the numerator.

2) Write the product of the unit fraction’s denominator and the whole number, for the new denominator.

Example: let’s divide 1/5 by 8.

The numerator is 1.
The new denominator is 5 x 8 = 40.

Have a blessed, wonderful day!
• help me I don't get it
• Think about it. You have a cake and it is in 5 equal parts. One of the pieces is 1/5, but then you split it into 3 more pieces,so, one piece of the cake is now 1/15. But don't worry you will get it if you think of it as cake.
• How would you show it on a number line, though?
• you take the reciprocal of 3/1 which is 1/3 and then you would do 1/3 x 1/5 and get 1/15 and then you take the denominator and put the denominator as the total number of points and split it into 3 groups of 5.
• use a box if you need a visual representation
• That's what I use sometimes.
• By some coincidence I get both of the questions in there ...
• this is kinda hard. is it to you?
• It's not super hard once you understand it.
• ok so its multiplication not division?
