Concept of Estimation in Percentage:

Percentages help us to estimate the parts of an area.

What percent of the following figure is shaded?


Solution:

We first find the fraction of the figure that is shaded. From this fraction, the percentage of the shaded part can be found.

`1/4 xx 100 = 25%`

`1/8 xx 100 = 12.5%`

`1/8 xx 100 = 12.5%`

Thus, Total percentage of the shaded part = 25% + 12.5% + 12.5%.

Thus, 50 % of the figure is shaded.
