Chapter 5.1, Problem 79E
Egyptian mathematics had a unique way of writing fractions as sums of unit fractions – that is, fractions of the form
1n. For example, the fraction
29 could be written as
16+118 and also as
15+145. They would not represent a number like
23 as
13+13 ; they would use two different unit fractions. Unit fractions were written by placing the symbol 
, which looked somewhat like an eye, over the numeral. For example,
13 could be written as
. In exercises
79 − 82, write the given fractions as the sum of unit fractions, using our common notation rather than the cumbersome Egyptian notation. (There may be several correct answers but we will give only one.)
