Convert 1.3×10^2 mL to deciliters (dL).

• A. 0.13 dL
• B. 1.3 dL
• C. 13 dL
• D. 130 dL

Answer: (B)

In metric volume, 1 deciliter equals 100 milliliters (since 1 liter is 1000 mL and 1 liter equals 10 dL, so 1 dL = 0.1 L = 100 mL). Start by converting the given amount to milliliters: 1.3×10^2 mL is 130 mL. Now convert to deciliters by dividing by 100: 130 mL ÷ 100 = 1.3 dL. So the correct result is 1.3 dL.

Quick check: 0.13 dL would be 13 mL, 13 dL would be 1300 mL, and 130 dL would be 13,000 mL.
