\newline

The decimal grid shown below is shaded and marked with

X_{s}

to model an expression.

\newline

Which expression could be modeled by this decimal grid?

\newline

A

0.08 \times 0.04

\newline

B

0.08 \times 0.40

\newline

C

0.80 \times 0.04

\newline

D

0.80 \times 0.40

Count Total Squares: Count the total number of squares in the grid to find out the whole. $\newline$ Total squares = $10 \times 10 = 100$ squares.
Count Shaded Squares: Count the number of shaded squares marked with X to find the part of the grid that's shaded. $\newline$ Shaded squares = $8 \times 4 = 32$ squares.
Calculate Decimal Equivalent: Calculate the decimal equivalent of the shaded part by dividing the number of shaded squares by the total number of squares. $\newline$ Decimal equivalent = Shaded squares / Total squares = $\frac{32}{100} = 0.32$ .
