Please consider the attached image as the given square.
We are asked to express the shaded area as a fraction, a decimal, and a percent of the whole.
We can see that in our figure there are 100 squares as there are 10 rows and each row contains 10 squares.
We can also see that there are 81 shaded squares out of 100 squares, so we can represent it as a fraction as:
To convert the shaded area into decimal, we need to divide 81 by 100.
To convert the shaded area into percent, we need to multiply 0.81 by 100.

Answer:
179/495
Step-by-step explanation:
When the repeating decimal starts at the decimal point, the repeating digits can be turned into a fraction by putting them over the same number of 9s. That is, 0.61616161... is equivalent to 61/99.
Here, the repeating part is 1/10 that value, so is 61/990. This is added to the non-repeating part, which is 0.3 = 3/10.
Then the entire decimal is ...
0.361_61 = 3/10 + 61/990 = (297 +61)/990 = 358/990 = 179/495
