# Euler's Theorem

\[ \dfrac1{24} , \dfrac{2}{24}, \dfrac{3}{24}, \ldots , \dfrac{23}{24}, \dfrac{24}{24} \]

How many of the fractions above **cannot** be reduced?

\[ \dfrac1{32} , \dfrac{2}{32}, \dfrac{3}{32}, \ldots , \dfrac{31}{32}, \dfrac{32}{32} \]

Which of the following is true regarding the 32 fractions above?

**Statement 1**: The number of fractions that cannot be reduced is less than the number of fractions that can be reduced.

**Statement 2**: The number of fractions that cannot be reduced is equal to the number of fractions that can be reduced.

**Statement 3**: The number of fractions that cannot be reduced is greater than the number of fractions that can be reduced.
