What is the decimal form of 1/5?

• A. 0.1
• B. 0.2
• C. 0.4
• D. 0.6

Answer: (B)

Dividing 1 by 5 gives the decimal form. In long division, 1 ÷ 5 is 0 with a remainder of 1; bringing down a zero makes 10, and 5 goes into 10 two times, leaving no remainder. So 1/5 = 0.2. Another way to see it is to scale the fraction: multiply numerator and denominator by 2 to get 2/10, which is the same as 0.2. The other options represent different fractions: 0.1 is 1/10, 0.4 is 2/5, and 0.6 is 3/5, so they don’t match 1/5.
