abb0t · Answer

Find a common denominator.
For this example, your common denominator is: 15x
That might help guide you.

anonymous · Answer

what do i do with the common denominator would i get 3+2/15x?

abb0t · Answer

Well, you know:
$$\frac{ 2 }{ a } + \frac{ 1 }{ a } = \frac{ 2 + 1 }{ a } = \frac{ 3 }{ a }$$

abb0t · Answer

Also,
$$\frac{ 1 }{ b } + \frac{ 3 }{ d } = \frac{ 1d + 3b }{ bd }$$

anonymous · Answer

so my final answer would be 5/15x?

abb0t · Answer

Not quite. Because in order to get a 15x, you must multiply 3 by x and 2 by 15.

$$\frac{ 3 }{ 15 } + \frac{ 2 }{ x } = (\frac{ 3x }{ 15x }) + (\frac{ 2(15) }{ 15x })$$

abb0t · Answer

The next step is to combine everything into one whole fraction.
