Concept of Estimation in Percentage:

Percentages help us to estimate the parts of an area.

What percent of the following figure is shaded?


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.
