Question

Rút gọn phan sô:

\(\frac{1339}{1442}\)và \(\frac{1212}{3030}\)

Answer 1

\(\frac{1339}{1442}=\frac{13}{14}\)

\(\frac{1212}{3030}=\frac{2}{5}\)

Answer 2

\(\frac{1339}{1442}=\frac{1300+39}{1400+42}=\frac{13\times100+13\times3}{14\times100+14\times3}=\frac{13\times\left(100+3\right)}{14\times\left(100+3\right)}=\frac{13}{14}\)\(\frac{13}{14}\)

\(\frac{1212}{3030}=\frac{1200+12}{3000+30}=\frac{12\times100+12}{30\times100+30}=\frac{12\times\left(100+1\right)}{30\times\left(100+1\right)}=\frac{12}{30}=\frac{2}{5}\)

Answer 3

\(\frac{1339}{1442}=\frac{13}{14}\)

\(\frac{1212}{3030}=\frac{2}{5}\)K.quả như vậy nha bn .
