Question

\(3\dfrac{7}{8}\times x-2\dfrac{3}{4}=3\dfrac{6}{12}\times\dfrac{10}{8}-\dfrac{1}{3}\)

cíuuuuuu

Answer 1

\(3\dfrac{7}{8}\times x-2\dfrac{3}{4}=3\dfrac{6}{12}\times\dfrac{10}{8}-\dfrac{1}{3}\)

\(\dfrac{31}{8}\times x-\dfrac{11}{4}=\dfrac{7}{2}\times\dfrac{10}{8}-\dfrac{1}{3}\)

\(\dfrac{31}{8}\times x-\dfrac{11}{4}=\dfrac{35}{8}-\dfrac{1}{3}\)

\(\dfrac{31}{8}\times x=\dfrac{97}{24}+\dfrac{11}{4}\)

\(\dfrac{31}{8}\times x=6\dfrac{19}{24}\)

\(x=1\dfrac{70}{93}\)

Answer 2

42/12x10/8-1/3= 84/24x30/24-8/24= 315/72-8/24= 291/72

xong bạn rút gọn nha
