8x+\frac{3x}{2\times 2}+\frac{2}{3}
Multiply \frac{1}{2} times \frac{3x}{2} by multiplying numerator times numerator and denominator times denominator.
8x+\frac{3\times 3x}{12}+\frac{2\times 4}{12}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 2\times 2 and 3 is 12. Multiply \frac{3x}{2\times 2} times \frac{3}{3}. Multiply \frac{2}{3} times \frac{4}{4}.
8x+\frac{3\times 3x+2\times 4}{12}
Since \frac{3\times 3x}{12} and \frac{2\times 4}{12} have the same denominator, add them by adding their numerators.
8x+\frac{9x+8}{12}
Do the multiplications in 3\times 3x+2\times 4.
\frac{12\times 8x}{12}+\frac{9x+8}{12}
To add or subtract expressions, expand them to make their denominators the same. Multiply 8x times \frac{12}{12}.
\frac{12\times 8x+9x+8}{12}
Since \frac{12\times 8x}{12} and \frac{9x+8}{12} have the same denominator, add them by adding their numerators.
\frac{96x+9x+8}{12}
Do the multiplications in 12\times 8x+9x+8.
