Question

B=\(\left(6\frac{4}{9}+3\frac{7}{11}\right)-4\frac{4}{9}\)

C=\(\frac{-5}{7}x\frac{2}{11}+\frac{-5}{7}x\frac{9}{11}+1\frac{5}{7}\)

D=\(0,7x2\frac{2}{3}x20x0,375x\frac{5}{28}\)

E=(-6,17+\(3\frac{5}{9}-2\frac{36}{97}\))x\(\left(\frac{1}{3}-0,25-\frac{1}{2}\right)\)

giúp mình gấp nha ai lam dc câu nào thì làm

Answer 1

B=\(6\frac{4}{9}-4\frac{4}{9}+3\frac{7}{11}\)

B=\(2+3\frac{7}{11}\)

B=\(5\frac{7}{11}\)

Answer 2

B = \(5\frac{7}{11}=\frac{62}{11}\)

C = 1

D = \(\frac{5}{2}=2\frac{1}{2}\)

Answer 3

giup mink đi

Answer 4

co the lam ro hon dc ko
