3%

Explanation:

So in the most basic form, this question is asking what percent of $1,800 is$53.60. To find the percentage, we are simply going to divide both numbers then multiply by 100.

I'd like to add that by multiplying by 100, we change the number to a percentage. If we were to skip this step, it would just be a small decimal and not in the correct format needed for the answer.

$= \left(\frac{53.60}{1800}\right) \cdot 100$

$= \left(0.02977777777\right) \cdot 100$

= 2.97777777778%

All that is left is to round to the tenths place! Here is a super helpful chart on what the different place values are:
We see that the tenths place is is number immediately after the decimal. We know that we will be rounding $9$. To do this we just look at the number just to the right of it, $7$, and if it's above $5$ we will round it up.

Since it is, we round the entire number up to our final answer of 3%.

Hope this helped!
