Answer:
The set of all positive proper fractions with a denominator of 7 is [tex]\text S=[\frac{1}{7},\ \frac{2}{7},\ \frac{3}{7},\ \frac{4}{7},\ \frac{5}{7},\ \frac{6}{7}][/tex].
Step-by-step explanation:
A proper fraction is of the form [tex]\frac{x}{y}[/tex] where the numerator is less than the denominator, i.e. x < y.
A set is a collection of items that belong to a certain experiment. Every member of a set are known as elements.
In this case we need to form a set of all positive proper fractions with a denominator of 7.
So, it is provided that y = 7.
Then the value of x has to be positive and less than 7, i.e. 1 < x < 7.
The set is:
[tex]\text S=[\frac{1}{7},\ \frac{2}{7},\ \frac{3}{7},\ \frac{4}{7},\ \frac{5}{7},\ \frac{6}{7}][/tex]
Thus, the set of all positive proper fractions with a denominator of 7 is [tex]\text S=[\frac{1}{7},\ \frac{2}{7},\ \frac{3}{7},\ \frac{4}{7},\ \frac{5}{7},\ \frac{6}{7}][/tex].
