Answer:

55%

Step-by-step explanation:

to find percentages:

$\frac{part}{whole}$ I $\frac{percent}{100}$     pretend this is a box

basically just fill this in and it will give you what you want. For example, here, you have the original and part of the original so it will look like this:

$\frac{99}{180}$ I $\frac{x}{100}$ then you multiply across and divide top to bottom (doesn't matter in which order), so: $\frac{99}{180}$ =0.55 · 100 = 55%.
