To find the number of millimeters in 8 inches using the given equivalent ratios, you can set up a proportion based on the information:
\[ \frac{8 \text{ inches}}{x \text{ mm}} = \frac{40 \text{ inches}}{1016 \text{ mm}} \]
Now, cross-multiply to solve for \(x\):
\[ 8 \text{ inches} \times 1016 \text{ mm} = 40 \text{ inches} \times x \text{ mm} \]
This simplifies to:
\[ 8128 = 40x \]
Now, divide both sides by 40 to isolate \(x\):
\[ x = \frac{8128}{40} = 203.2 \]
Thus, there are 203.2 mm in 8 inches.
So the correct answer is 203.2 mm.
