Write a word problem using 3/4•4/5

Think about it this way:

By saying 3/4 x 4/5 you are saying 3/4 OF 4/5

So you can make a problem where 4/5 of something is leftover (perhaps in food? Or a job?) and say a person finished 3/4 of that leftover whatever. The question would be: how much of the WHOLE thing did the person finish?

Ex/

Bob and Jon are arranging books from a box. Jon arranges 1/5 of the books, leaving the rest to Bob. Bob arranges 3/4 of the rest. How much of the whole box of books did Bob arrange?

-

So in this problem, Jon arranged 1/5 of the books. Which means, the “rest” is 4/5 of the whole box left for Bob.

Bob decides to only 3/4 OF that 4/5 that is left for him.

-

The question asks: How much OF the whole box of books did Bob arrange?

To find that, you would do 3/4 x 4/5.

3/4x4/5 = 12/20 and when simplified, (divide the numerator and denominator by 4)

=3/5

That will be the answer. Bob arranges 3/5 of all the books.

Hope this helps!!

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
