the equation can be writen like:
[tex]\frac{\frac{14}{15}}{\frac{4}{5}}[/tex]So we can operate the numerator of the first fraction by the denominator of the secon fraction, and the denominator of the fist equation by the numetator of the second fraction so:
[tex]\frac{14\cdot5}{15\cdot4}=\frac{70}{60}=\frac{7}{6}[/tex]
