Example of Use of Number times Recurring Part of Reciprocal gives 9-Repdigit
\(\ds \dfrac 1 {37}\) | \(=\) | \(\ds 0 \cdotp \dot 0 2 \dot 7\) | ||||||||||||
\(\ds 27 \times 37\) | \(=\) | \(\ds 10^3 - 1\) |
Proof
Let $x = \dfrac 1 {37} = 0 \cdotp \dot 0 2 \dot 7$.
Then $n = 37$; $m = 27$ and $d = 3$
Therefore:
- $27 \times 37 = 10^3 - 1$
$\blacksquare$
