Explanation:
\(0.0001\)
For option (a), \(0.0001=\frac{1}{10000}\)
For option (b), \(\frac{1}{10000}\)
For option (c), \(\frac{1}{10^{6}}=\frac{1}{10\times10\times10\times10\times10\times10}\)
\(=\frac{1}{1000000}\)
For option (d), \(\frac{1}{10^{6}}+0.1=\frac{1}{0.1}\times\frac{1}{0.1}\)
\(=\frac{1}{10^{6}}\times\frac{10}{1}=\frac{10}{10^{6}}=\frac{1}{10^{5}}\)
\(=\frac{1}{10\times10\times10\times10\times10}\)
\(=\frac{1}{100000}\)
The fraction whose denominator is smallest wil be largest.
Hence, (a) and (b) are the largest.
