Convert 2/5 to a decimal.

Explanation:
Converting a fraction to a decimal is done by dividing the top number by the bottom number. For 2/5, divide 2 by 5. 5 goes into 2.0 zero times, then 5 goes into 20 four times, giving 0.4. So the decimal form is 0.4. Another way to see it is multiply numerator and denominator by 2 to get 4/10, which equals 0.4. This illustrates why the decimal terminates after one place. The other options don’t match because 0.2 would be 1/5, 0.5 would be 1/2, and 0.04 would be 1/25.
