\frac{\frac{6y}{y}+\frac{4}{y}}{2+\frac{6}{y}}
To add or subtract expressions, expand them to make their denominators the same. Multiply 6 times \frac{y}{y}.
\frac{\frac{6y+4}{y}}{2+\frac{6}{y}}
Since \frac{6y}{y} and \frac{4}{y} have the same denominator, add them by adding their numerators.
\frac{\frac{6y+4}{y}}{\frac{2y}{y}+\frac{6}{y}}
To add or subtract expressions, expand them to make their denominators the same. Multiply 2 times \frac{y}{y}.
\frac{\frac{6y+4}{y}}{\frac{2y+6}{y}}
Since \frac{2y}{y} and \frac{6}{y} have the same denominator, add them by adding their numerators.
\frac{\left(6y+4\right)y}{y\left(2y+6\right)}
Divide \frac{6y+4}{y} by \frac{2y+6}{y} by multiplying \frac{6y+4}{y} by the reciprocal of \frac{2y+6}{y}.
\frac{6y+4}{2y+6}
Cancel out y in both numerator and denominator.
\frac{2\left(3y+2\right)}{2\left(y+3\right)}
Factor the expressions that are not already factored.
\frac{3y+2}{y+3}
Cancel out 2 in both numerator and denominator.
\frac{\frac{6y}{y}+\frac{4}{y}}{2+\frac{6}{y}}
To add or subtract expressions, expand them to make their denominators the same. Multiply 6 times \frac{y}{y}.
\frac{\frac{6y+4}{y}}{2+\frac{6}{y}}
