If a round rod has a radius of 11/32 inches, what is its diameter in inches as a decimal?

Explanation:
Doubling the radius gives the diameter. With a radius of 11/32 inch, the diameter is 2 × 11/32 = 22/32 = 11/16. Convert to decimal: 11/16 = 0.6875 (since 11 ÷ 16 = 0.6875). The other decimals correspond to different fractions (0.625 = 5/8, 0.4375 = 7/16, 0.75 = 3/4), so they don’t match 11/16. The diameter is 0.6875 inches.
