\(\dfrac{13}{50}+9\%+\dfrac{41}{100}+0,24\)

Answer 1

\(\dfrac{13}{50}+9\%+\dfrac{41}{100}+0,24\)

\(=\dfrac{13}{50}+\dfrac{9}{100}+\dfrac{41}{100}+\dfrac{6}{25}\)

\(=\dfrac{13}{50}+\dfrac{9}{100}+\dfrac{41}{100}+\dfrac{12}{50}\)

\(=\left(\dfrac{13}{50}+\dfrac{12}{50}\right)+\left(\dfrac{9}{100}+\dfrac{41}{100}\right)\)

\(=\dfrac{25}{50}+\dfrac{50}{100}\)

\(=\dfrac{25}{50}+\dfrac{25}{50}\)

\(=\dfrac{50}{50}=1\)

Answer 2

\(\dfrac{13}{50}+9\%+\dfrac{41}{100}+0,24\)

\(=\dfrac{26}{100}+\dfrac{9}{100}+\dfrac{41}{100}+\dfrac{24}{100}\)

\(=\left(\dfrac{26}{100}+\dfrac{24}{100}\right)+\left(\dfrac{9}{100}+\dfrac{41}{100}\right)\)

\(=\dfrac{50}{100}+\dfrac{50}{100}=\dfrac{1}{2}+\dfrac{1}{2}=\dfrac{2}{2}=1\)
