Question

đề bài là tính nha

Answer 1

\(d,=\left(-\dfrac{5}{12}-\dfrac{7}{12}\right)+\left(-3,7-6,3\right)\\ =-\dfrac{12}{12}-10\\ =-1-10\\ =-11\)

Answer 2

\(-\dfrac{5}{12}+\left(-3,7\right)-\dfrac{7}{12}-6,3\)

\(=-\dfrac{5}{12}+\left(-\dfrac{37}{10}\right)-\dfrac{7}{12}-\dfrac{63}{10}\)

\(=-11\)

Answer 3

\(d,-\dfrac{5}{12}+\left(-3,7\right)-\dfrac{7}{12}-6,3\)

\(=\left(-\dfrac{5}{12}-\dfrac{7}{12}\right)+\left(-3,7-6,3\right)=\left(-1\right)+\left(-10\right)=-11\)
