= 1 nha bạn !

làm thế nào bạn ơi

\(1\frac{13}{15}.\left(0,5\right)^2.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)

\(=1\frac{13}{15}.0,25.3+\left(-\frac{47}{60}\right):1\frac{23}{24}\)

\(=1\frac{13}{14}.0,75+\left(-\frac{2}{5}\right)\)

\(=1,4-0,4\)

\(=1\)

\(1\frac{13}{15}.\left(0,5\right)^2.3+\left(\frac{8}{15}-1\frac{19}{60}\right);1\frac{23}{24}=\frac{7}{5}+\left(-\frac{2}{5}\right)=1\)

bằng 1

=28/15 x 0,25 x 3 + (8/15 - 79/60) : 47/24

= 28/15 x 0,25 x 3 + (-47/60) : 47/24

Bạn tự tính kết quả theo lần lượt nhé 

kết quả : 1

tick cho mk nhé

\(1\frac{13}{15}:\left(0,5\right)^2.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}=\frac{28}{15}.12+\left(\frac{8}{15}-\frac{79}{60}\right).\frac{24}{47}\)

                                                                         \(=\frac{112}{5}+\left(-\frac{47}{60}.\frac{24}{47}\right)\)

                                                                         \(=\frac{112}{5}-\frac{2}{5}\)

                                                                        \(=\frac{100}{5}=20\)

Study well ! >_<

\(1\frac{13}{15}:0,5^2.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)

\(=\frac{28}{15}:0,25.3+\left(\frac{8}{15}-\frac{79}{60}\right):\frac{47}{24}\)

\(=\frac{112}{15}.3+\left(\frac{32}{60}-\frac{79}{60}\right):\frac{47}{24}\)

\(=\frac{112}{5}+\frac{-47}{60}:\frac{47}{24}\)

\(=\frac{112}{5}+\frac{-47}{60}.\frac{24}{47}\)

\(=\frac{112}{5}+\frac{-1}{5}.\frac{2}{1}\)

\(=\frac{112}{5}+\frac{-2}{5}\)

\(=\frac{110}{5}\)

\(=\frac{22}{1}=22\)
