A coach found that 2/5 of the baseball team reported for spring training in good physical condition. What is the decimal representation for that fraction?

• A. 0.125
• B. 0.2
• C. 0.35
• D. 0.4

Answer: (D)

Converting a simple fraction to a decimal. For 2/5, think that 1/5 is 0.2, so 2/5 is twice that, which is 0.4. Another way is to multiply top and bottom by 2 to get 4/10, and 4/10 equals 0.4. So the decimal representation is 0.4. The other options come from different fractions: 0.125 is 1/8, 0.2 is 1/5, and 0.35 is 7/20, none of which equal 2/5.
