( 1/2 + 1/6 + 1/12 + 1/30 ) : ( 1/3 + 1/6 + 1/12 + 1/ 24 + 1/48 )=(1/1.2 + 1/2.3 + 1/3.4 +1/5.6 ):(1/3.1 +1/3.2 + 1/3.4 + 1/3.8 +1/3.16)=....

Answer 2

[๖ACE✪ʟê❖тʀí❖тιêɴ︵²⁰⁰7 (TMS)★]

\(\left(\frac{1}{2}+\frac{1}{6}+\frac{1}{12}+\frac{1}{30}\right):\left(\frac{1}{3}+\frac{1}{6}+\frac{1}{12}+\frac{1}{24}+\frac{1}{48}\right)\)

\(=\left(\frac{12}{12}+\frac{2}{12}+\frac{1}{12}+\frac{1}{30}\right):\left(\frac{16}{16}+\frac{8}{48}+\frac{4}{48}+\frac{2}{48}+\frac{1}{48}\right)\)

\(=\left(\frac{15}{12}+\frac{1}{30}\right):\frac{31}{48}\)

\(=\left(\frac{225}{180}+\frac{6}{180}\right):\frac{31}{48}\)

\(=\frac{231}{180}:\frac{31}{48}\)

\(=\frac{231}{180}.\frac{48}{31}=\frac{231.24}{90.31}\)

\(=\frac{5544}{2790}\)nếu rút gọn được thì bạn rút gon luôn nhé
