10 inches is approximately how many meters?

The correct answer is: 1/4

To convert inches to meters, it is useful to know that 1 inch is approximately equal to 0.0254 meters. Therefore, to convert 10 inches into meters, you would multiply 10 by 0.0254. The calculation would be: 10 inches × 0.0254 meters/inch = 0.254 meters. When considering the choices provided, the closest approximate value to 0.254 meters is 1/4 meter, which is equivalent to 0.25 meters. This rounding aligns well with basic measurement conversions and approximations commonly used in practical settings. The other options represent values that are either significantly smaller or larger when compared to the accurate conversion of 10 inches to meters, making them less appropriate in this context. Thus, selecting 1/4 as the approximate value accurately reflects the conversion from inches to meters.
