Math CentralQuandaries & Queries


Question from Marouf, a student:

How can you make a word problem for 6 2/3 and solve the word problem? I'm having trouble. Please help

Hi Marouf.

Penny is a window washer on a high-rise office tower. She works fast -- she can complete all the windows on a floor in 20 minutes. There are 20 stories on the building. How many hours does it take her to do the whole building?

Start by changing 20 minutes into a fraction of an hour. Then multiply by 20. Then convert that to a mixed fraction.

Stephen La Rocque.
