The model of the shaded region is 0.80. And if 8 square boxes were shaded, then Koran's model was right.
A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Koran showed 0.08 with the model.
In the model,
there are ten columns and ten rows.
That means, 100 square boxes.
And the shaded region have 8 columns and 10 rows.
That means, 80 square boxes.
Koran showed the percentage of shaded region of the model.
That is, 0.08 is 8%.
So let n be the percentage of shaded region.
So, 80 =n x 100/ 100
n = 80%
And 80% in decimal is 0.80.
And if Koran wants 0.08.
That means, 8% of shaded region.
So 8% 0f 100 is 8 square boxes.
Therefore, if 8 square boxes were shaded, then Koran's model was right.
