Giúp mình làm đề cương

Answer 1

bạn trg nào

Answer 2

\(\frac{-7}{12}+\frac{11}{8}-\frac{5}{9}\)

\(=\frac{-42}{72}+\frac{99}{72}+\frac{-40}{72}\)

\(=\frac{17}{72}\)

Answer 3

sorry, i can't anwer your question.

Answer 4

\(\frac{1}{7}-\frac{8}{7}:8-3:\frac{3}{4}.\left(-2\right)^2\)

\(=\frac{1}{7}+\frac{-1}{7}+\left(-16\right)\)

\(=0+\left(-16\right)\)

\(=-16\)

Answer 5

Roronoa Zoro dấu trừ nhé!

\(\frac{-7}{12}+\frac{11}{8}-\frac{5}{9}\)

\(=\frac{-42}{72}+\frac{99}{72}-\frac{-40}{42}\)

\(=\frac{97}{72}\)
