Lesson 4: Dividing fractions and whole numbers word problems

# Dividing fractions and whole number word problems

This video uses tape diagrams to visually represent division with fractions. It shows how to divide a fraction or a whole number into equal parts. Tape diagrams help us see the process in a clear, simple way.

• Could you just do 1/4 divided by 2 much simpler? I think you can
• yes you can i agree sertantly
• Also, why are they called "tape diagrams"?
• Hi there! tape diagram is called like that, because they look like tape. Hope this helped, (this is from grammar but I will do this here X-D) you can learn anything, Joy out!
• There is no single division problem that is the hardest one in the world. When working division problems by hand, some people find one kind of problem harder than others, but everyone would not agree on which problem is hardest. When using a computer or calculator, all division problem have essentially equal difficulty.

There is no definitive answer to that, as difficulty will differ from person to person. One could argue that there are degrees of difficulty in different types of division problems. For instance:

1 / 1 might be one of the easiest possible ones.
2 / 1 could arguably be a little more difficult
4 / 2 may perhaps be a little more difficult than that
7 / 2 a bit harder
3 / 7 harder still
pi / 7 again perhaps harder
pi / √2 may be even more so
These are very subjective statements. This order may make sense some, but to others, it may be easier to divide seven by two than four by two. This is akin to asking whose face is the prettiest. You could get a billion different answers and all of them correct from the point of view of those giving the answer.

Another point to made here is that it may not be possible to define a "hardest" division problem, as one could argue that it's always possible to take an existing problem and make it more difficult. This would be comparable to asking what the highest number is.
• For questions like this, you can just multiply the whole number times the denominator. For example, if you had 5 divided by 2/3, you would multiply 5 times 3 and you will get 15.
• it's 4 x 2 = 8 then make it a fraction make 8 denominators and make 1 numerator
• wait.. Why do we have to divide the fourth Square by 2.?
• you can divide by 2 in the frst 1.
