Bài làm

\(A=1\frac{6}{41}.\left(\frac{12+\frac{12}{19}+\frac{12}{37}-\frac{12}{53}}{3+\frac{3}{19}+\frac{3}{37}-\frac{3}{53}}:\frac{4+\frac{4}{19}+\frac{4}{37}-\frac{4}{53}}{5+\frac{4}{19}+\frac{4}{37}-\frac{4}{53}}\right).\frac{124242423}{237373735}\)

\(A=\frac{47}{41}.\left(\frac{12+12.\frac{1}{19}+12.\frac{1}{37}-12.\frac{1}{53}}{3+3.\frac{1}{19}+3.\frac{1}{37}-3.\frac{1}{53}}:\frac{4+4.\frac{1}{19}+4.\frac{1}{37}-4.\frac{1}{53}}{5+4.\frac{1}{19}+4.\frac{1}{37}-4.\frac{1}{53}}\right).\frac{124242423}{237373735}\)

\(A=\frac{47}{41}.\left(\frac{12.\left(1+\frac{1}{19}+\frac{1}{37}-\frac{1}{53}\right)}{3.\left(1+\frac{1}{19}+\frac{1}{37}-\frac{1}{53}\right)}:\frac{4.\left(\frac{1}{19}+\frac{1}{37}-\frac{1}{53}\right)+1}{5.4.\left(\frac{1}{19}+\frac{1}{37}-\frac{1}{53}\right)}\right).\frac{124242423}{237373735}\)

\(A=\frac{47}{41}.\left(\frac{12.1}{3.1}:\frac{4.+1}{5.4.}\right).\frac{124242423}{237373735}\)

\(A=\frac{47}{41}.\left(\frac{12}{3}:\frac{5}{20.}\right).\frac{124242423}{237373735}\)

\(A=\frac{47}{41}.\left(\frac{12}{3}x\frac{20}{5}\right).\frac{124242423}{237373735}\)

\(A=\frac{47}{41}.\frac{80}{5}.\frac{124242423}{237373735}\)

\(A=\frac{47}{41}.16.\frac{124242423}{237373735}\)

~ Đến đây tự tính tiếp, bn rút gọn tử phân số \(\frac{124242423}{237373735}\)này thử xem, mik k chắc là rút gọn đc, xg bn tính như bình thường nhé ~
