pr014-1.jpg Use pencil and paper to answer the question.
Writing Egyptian Fractions

A fifth grade class was doing research about fractions. They’ve found that the ancient Egyptians wrote all of their fractions as a sum of unit fractions where
no unit fraction is repeated.
For example, you cannot write pr014-2.jpg One way to write it would be pr014-3.jpg
An algorithm for finding a unit fraction expression for any fraction is
the Greedy Method. To use the Greedy Method on fraction X:
Start with the largest unit fraction less than fraction X. Then continue in the same manner to represent the remaining value.
Example: Represent pr014-4.jpg as a sum of unit fractions.
Step 1: pr014-5.jpgpr014-6.jpg is the largest unit fraction pr014-7.jpg
Step 2: pr014-8.jpgpr014-9.jpg is the largest unit fraction pr014-10.jpg
a. Represent pr014-11.jpg as a sum of unit fractions. Show all of your work.
Explain your thinking.






b. Represent pr014-12.jpg as a sum of unit fractions in a different way.
Show all of your steps.
