a, x=    -8/3

b, x=    -3/22

7/48 - (1/2 x 2 + 1/6 x 4 + 1/8 x 5 + 1/12 x 7 + 1/14 x 8) : x = 0

7/48 - (1 + 2/3 + 5/8 + 7/12 + 4/7) : x = 0 (đã rút gọn)

7/48 - (336/336 + 224/336 + 210/336 + 196/336 + 192/336) : x = 0 (quy đồng)

7/48 - 193/56 : x  = 0

193/56 : x = 0 + 7/48

193/56 : x = 7/48

              x = 193/56 : 7/48

              x = 1158/49

Bài 1

a) MC: 75

\(\frac{7}{-15}=\frac{-7}{15}=\frac{-7.5}{15.5}=\frac{-35}{75}\)

\(\frac{-8}{-25}=\frac{8}{25}=\frac{8.3}{25.3}=\frac{24}{75}\)

\(\frac{11}{-75}=\frac{-11}{75}\)

b) MC: 180

Cách làm tương tự

Bài 2:

\(\frac{-1}{8}=\frac{-3}{24}\)

\(\frac{2}{-3}=\frac{16}{-24}=\frac{-16}{24}\)

\(\frac{3}{-72}=\frac{1}{-24}=\frac{-1}{24}\)

\(\frac{5}{-6}=\frac{20}{-24}=\frac{-20}{24}\)

Bài 3:

\(1=\frac{16}{16}\)

\(\frac{5}{-8}=\frac{-10}{16}\)

\(0=\frac{0}{16}\)
