=43/12-16/6.(20/32+7/32)
=43/12-16/6.27/32
=43/12-9/4
=43/12-27/12
=4/3
43/12-16/6x[5/8+7/32]
=43/12-16/6x[20/32+7/32]
=43/12-16/6x27/32
=43/12-432/192
=688/192-432-192
=256/192=4/3
\(\frac{43}{12}-\frac{16}{6}\times(\frac{5}{8}+\frac{7}{32})\)
\(=\frac{43}{12}-\frac{8}{3}\times(\frac{5}{8}+\frac{7}{32})\)
\(=\frac{43}{12}-\frac{8}{3}\times\frac{5}{8}-\frac{8}{3}\times\frac{7}{32}\)
\(=\frac{43}{12}-\frac{5}{3}-\frac{7}{12}\)
\(=\frac{43}{12}-\frac{20}{12}-\frac{7}{12}\)
\(=\frac{16}{12}=\frac{4}{3}\)
Chúc bạn học tốt
