Question

Tính bằng cách thuận tiện:

\(15\frac{2}{3}:3+12\frac{1}{3}:3-\frac{8}{3}\)

(Các bạn nhớ ghi rõ bài giải nhé)

Answer 1

\(=\left(15\frac{2}{3}+12\frac{1}{3}\right):3-\frac{8}{3}\)

\(=28:3-\frac{8}{3}\)

\(=\frac{28}{3}-\frac{8}{3}\)

\(=\frac{20}{3}\)

Answer 2

\(15\frac{2}{3}:3+12\frac{1}{3}:3-\frac{8}{3}\)

\(=\left(15\frac{2}{3}+12\frac{1}{3}\right):3-\frac{8}{3}\)

\(=28:3-\frac{8}{3}\)

\(\frac{28}{3}-\frac{8}{3}\)

\(\frac{20}{3}\)
