 Given \: rational \: number = \frac{45}{1200} \\= \frac{ 3 \times 3 \times 5 }{ 3 \times 2^{4} \times 5^{2}  } \\= \frac{ 3}{2^{4} \times 5 } \\= \frac{ 3\times 5^{3}}{2^{4} \times 5 \times 5^{3} } \\= \frac{ 3\times 125}{2^{4} \times 5^{4} } \\= \frac{ 375}{(2\times 5)^{4}  } \\= \frac{ 375}{10^{4}  } \\= \frac{375}{10000} \\= 0.0375 \: \blue { ( Terminating \: Decimal )}
