Answer 1

\(\dfrac{13}{50}+9\%+\dfrac{41}{100}+0,24\\ =\dfrac{13\times2}{100}+\dfrac{9}{100}+\dfrac{41}{100}+\dfrac{24}{100}\\ =\dfrac{26+9+41+24}{100}\\ =\dfrac{100}{100}=1\)

Answer 2

\(\dfrac{13}{50}+9\%+\dfrac{41}{100}+0,24=\dfrac{13\times2}{50\times2}+\dfrac{9}{100}+\dfrac{41}{100}+\dfrac{24}{100}=\dfrac{26+9+41+24}{100}=\dfrac{100}{100}=1\):V
