Question

[Trần Lã Chúc Quỳnh]

\(B=1.\frac{7}{20}:2,7+2,7:1,35+\left(0,4+2\frac{1}{2}\right)\times\left(4,2-1\frac{3}{10}\right)\)

  giải rỏ ràng dùm minh nha

Answer 1

[Natsu x Lucy]

\(B=1x\frac{7}{20}:2,7+2,7:1,35+\left(0,4+2\frac{1}{2}\right)x\left(4,2-1\frac{3}{10}\right)\)

\(B=\frac{7}{20}:2,7+2+2,9x2,9\)

\(B=\frac{7}{54}+2+8,41\)

\(B=10,53962963\)
