What is the correct relationship between 1 8 \frac{1}{8} 8 1 and 0.1 ?
1 8 < \frac{1}{8} \; < \; 8 1 < 0.1
1 8 > \frac{1}{8} \; > \; 8 1 > 0.1
They are equal
1 8 = \frac{1}{8} \; = \; 8 1 = 0.013
Show answer Answer: 1 8 > \frac{1}{8} \; > \; 8 1 > 0.1

A worked example
What is 1 5 \frac{1}{5} 5 1 written as a decimal?
We need to find the decimal form of 1 5 \frac{1}{5} 5 1 . To convert a fraction to a decimal, divide the numerator by the denominator.
Divide 1 ÷ 5 1 \; \div \; 5 1 ÷ 5 :
5 ) ‾ 0.2 5 ) 1.0 ‾ 10 ‾ 0 \begin{array}{r} \phantom{5\,\overline{\smash{\big)}\,}}0.2 \\ 5\,\overline{\smash{\big)}\,1.0} \\ \underline{10} \\ 0 \end{array} \\[6pt] 5 ) 0.2 5 ) 1.0 10 0 5 does not go into 1 (since 1 < 5), so the whole-number part is 0. We place a decimal point and bring down a 0 to continue dividing. Now we have 10. \\ 5 goes into 10 exactly 2 times → 5 × 2 = 10 \to 5 \times 2 = 10 → 5 × 2 = 10 . Subtract → 10 − 10 = 0 \to 10 - 10 = 0 → 10 − 10 = 0 . No remainder
Therefore 1 5 = \frac{1}{5} = 5 1 = 0.2 .
