680/11%

#### Explanation:

I think the easiest way to do this is by using proportions.

In this case, $55$ is the original and $34$ is part of $55$, so $55$ would be 100% and $34$ would be x%.

$\left(\frac{55}{100}\right)$ = $\left(\frac{34}{x}\right)$

Using cross multiplication you get:

$55 x = 3400$

$11 x = 680$

$x = \frac{680}{11}$

So $34$ is 680/11%# of $55$.
