We have to find out what the shaded regions represent. We can count up ten rectangles in total, and three of them are shaded. We take the amount of shaded rectangles over the total amount to get
as a fraction, and 0.3 as a decimal.
![\tt First~option:](https://img.qammunity.org/2021/formulas/mathematics/college/ijzubap938tuht0k1cn6gopr6s42mspw51.png)
The first choice is 0.300. The zeroes at the end of the number do not mean anything, so we can simplify it to 0.3. 0.3 is equal to 0.3, so this is not the answer.
![\tt Second~ option:](https://img.qammunity.org/2021/formulas/mathematics/college/tscz60m4yvygcuw5c68qxtk0nezafdoa8k.png)
The second choice is 0.30. Again, we can simplify it to 0.3. We can see that it is equivalent to 0.3, so this is not the answer, either.
![\tt Third~option:](https://img.qammunity.org/2021/formulas/mathematics/college/aj256rq0mlt4mntbifudap9epsb4h75l7d.png)
Our third choice is 0.3. 0.3 = 0.3, so this is not our answer either.
![\tt Fourth ~option:](https://img.qammunity.org/2021/formulas/mathematics/college/7b0cv6xxvzcavboll3jk8505no86sa49f6.png)
Our final choice is 0.030. Take out the last zero to get 0.03. 0.03 is equal to
, so this is our answer, since it is not 0.3.
