Five-eighths of a yard is the same as what percent of a yard?

This question assesses fraction-to-percent conversion. Start by converting the fractionto a decimal. Divide 5 by 8:

5 ÷ 8 = 0.625.

To convert a decimal to a percent, multiply by 100:

0.625 × 100 = 62.5%.

Therefore, the correct answer is C. The other options represent incorrect conversions: 37.5% equals, 22.5% is not a standard eighth fraction, and 40% equals. On the NEX exam, knowing common fraction-percent equivalents (such as 1/8 = 12.5%) can significantly reduce calculation time and improve accuracy.
