The question is an illustration of multiplication model.
The multiplication model is: [tex]\mathbf{0.90 \times 0.10 =0.09}[/tex]
From the figure, the shaded portions are:
[tex]\mathbf{Green = \frac{90}{100}}[/tex]
[tex]\mathbf{Orange = \frac{10}{100}}[/tex]
So, the multiplication model represents:
[tex]\mathbf{Model =Green \times Orange}[/tex]
This gives
[tex]\mathbf{Model =\frac{90}{100} \times \frac{10}{100}}[/tex]
Express as decimal
[tex]\mathbf{Model =0.90 \times 0.10}[/tex]
[tex]\mathbf{Model =0.09}[/tex]
Hence, the multiplication model is:
[tex]\mathbf{0.90 \times 0.10 =0.09}[/tex]
