What is a fraction?
Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have a total of 10 columns and 10 rows.
Total boxes = 10×10 ⇒ 100
Number of shaded boxes = 4×10 ⇒ 40
Each box contains X's out of 100 that is:
[tex]=\frac{40}{100}[/tex]
= 0.40
We can represent a number of columns in decimal such that:
[tex]=\frac{80}{100}[/tex]
= 0.80
The expression becomes 0.80×0.40
Thus, the expression 0.80×0.40 could be modeled by the given decimal grid option (D) is correct.
