Question

Tính :

\(A=\frac{28}{15}.\left(\frac{1}{2}\right)^2.3+\left(\frac{8}{15}-\frac{79}{60}\right).\frac{24}{47}\)

\(B=\frac{75}{100}.\frac{28}{15}-\left(\frac{104}{195}+\frac{25}{100}\right).\frac{24}{47}-\frac{51}{13}.\frac{1}{3}\)

Ai làm xong mk k nha!!!

Answer 1

mik ko ghi lại đề nhé!

\(A=\left(\frac{18}{15}.\frac{1}{4}.3\right)+\left(-\frac{47}{60}\right).\frac{24}{47}\)

\(A=\frac{8}{5}+\left(-\frac{2}{5}\right)\)

\(A=\frac{6}{5}\)

Answer 2

\(B=\frac{3}{4}.\frac{28}{15}-\left(\frac{8}{15}+\frac{1}{4}\right).\frac{24}{47}-\frac{17}{13}\)

\(B=\frac{7}{5}-\frac{47}{60}.\frac{24}{47}-\frac{17}{13}\)

\(B=\frac{7}{5}-\frac{2}{5}-\frac{17}{13}\)

\(B=1-\frac{17}{13}\)

\(B=-\frac{4}{13}\)
