tính nhanh:

13/15+9%+41/100+0,24

 

 

 

Answer 1

\(\dfrac{13}{15}+9\%+\dfrac{41}{100}+0,24=\dfrac{13}{15}+\dfrac{9}{100}+\dfrac{41}{100}+\dfrac{6}{25}=\left(\dfrac{13}{15}+\dfrac{6}{25}\right)+\left(\dfrac{9}{100}+\dfrac{41}{100}\right)=\dfrac{83}{75}+\dfrac{1}{2}=\dfrac{241}{150}\)

Answer 2

\(\dfrac{13}{15}+9\%+\dfrac{41}{100}+0,24\)

\(=\dfrac{13}{15}+\left(\dfrac{9}{100}+\dfrac{41}{100}+\dfrac{24}{100}\right)\)

\(=\dfrac{13}{15}+\dfrac{74}{100}\)

\(=\dfrac{260}{300}+\dfrac{222}{300}\)

\(=\dfrac{482}{300}=\dfrac{241}{150}\)
