What percentage does the shaded area of the figure represent?
It can be said with certainty that the shaded area is larger than half of the shape.
That is, the shaded part is more than 50%.
Therefore, we can disregard answers B and D.
The unshaded part is greater than 1% of the figure; it is not possible for 100 such parts to form the complete shape, therefore, we can disregard answer C.
Therefore, the correct answer must be 80%.
80%
Approximately what is \( \frac{11}{50} \) written as a percentage?
Look at the visual balance! If the shaded area clearly takes up more space than the unshaded area, it's definitely over 50%. In this rectangle, the shaded portion is obviously larger than the small unshaded strip.
The unshaded area is much larger than 1% of the total rectangle! If the answer were 99%, the unshaded part would be tiny - but you can see it's a substantial strip on the left side.
Yes! The formula is . But for visual estimation problems like this, you use logical reasoning and elimination instead.
Compare the sizes more carefully! Ask yourself: "Is the unshaded part about 1/5 of the total (suggesting 80%) or much smaller?" The visual evidence will guide you to the right choice.
Not for visual estimation! These problems test your ability to reasonably estimate proportions. Use your eyes to compare areas and logical thinking to eliminate impossible answers.
