\(\dfrac{5}{100}+\dfrac{12}{100}+\dfrac{100}{100}+\dfrac{9}{100}=\dfrac{126}{100}=\dfrac{63}{50}\)
\(\dfrac{5}{100}+\dfrac{6}{50}+\dfrac{2}{2}+\dfrac{9}{100}=\dfrac{5}{100}+\dfrac{12}{100}+\dfrac{100}{100}+\dfrac{9}{100}=\dfrac{5+12+100+9}{100}=\dfrac{126}{100}\)
\(\dfrac{5}{100}+\dfrac{6}{50}+\dfrac{2}{2}+\dfrac{9}{100}=\dfrac{5}{100}+\dfrac{12}{100}+\dfrac{100}{100}+\dfrac{9}{100}=\dfrac{126}{100}=\dfrac{63}{50}\)
\(\dfrac{5}{100}+\dfrac{6}{50}+\dfrac{2}{2}+\dfrac{9}{100}\)
\(=\dfrac{5}{100}+\left(\dfrac{6\times2}{50\times2}\right)+\left(\dfrac{2\times50}{2\times50}\right)+\dfrac{9}{100}\)
\(=\dfrac{5}{100}+\dfrac{12}{100}+\dfrac{100}{100}+\dfrac{9}{100}\)
\(=\dfrac{5}{100}+\dfrac{12}{100}+1+\dfrac{9}{100}\)
\(=\dfrac{17}{100}+1+\dfrac{9}{100}\)
\(=\dfrac{117}{100}+\dfrac{9}{100}\)
= \(\dfrac{126}{100}\)
= \(\dfrac{63}{50}\)
