Use a series to express the following number as a ratio of integers: 0.73737373

The number is 0.7373, and notice it is a repeating decimal. The solution is as follows:

Let x = 0.737373  eqn. 1

100x =73.737 eqn. 2

Subtracting the eqn 1 from eqn 2

99x = 73

x = 73/99

therefore the number could be expressed as 73/99

make sure you have version 2.50

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
