\(1\frac{13}{15}.0,75-\left(\frac{8}{15}+25\%\right)\)
\(=\frac{28}{15}.\frac{75}{100}-\left(\frac{8}{15}+\frac{25}{100}\right)\)
\(=\frac{7}{5}-\frac{47}{60}\)
\(=\frac{37}{60}\)
\(1\frac{13}{15}.0,75-\left(\frac{8}{15}+25\%\right)=\frac{28}{15}.\frac{3}{4}-\left(\frac{8}{15}+\frac{1}{4}\right)=\frac{7}{5}-\frac{8}{15}-\frac{1}{4}=\frac{37}{60}\)
bài này ra số dư to lắm bạn ơi , chắc là đề sai
Cho mk xin lỗi
\(1\frac{13}{15}×0,75-\left(\frac{8}{15}+25\%\right)\)
\(=\frac{28}{15}×0,75-\left(\frac{8}{15}+\frac{25}{100}\right)\)
\(=\frac{28}{15}×\frac{75}{100}-\left(\frac{8}{15}+\frac{25}{100}\right)\)
\(=\frac{28}{15}×\frac{3}{4}-\left(\frac{8}{15}+\frac{1}{4}\right)\)
\(=\frac{28}{15}×\frac{3}{4}-\frac{8}{15}-\frac{1}{4}\)
\(=\frac{7}{5}-\frac{8}{15}-\frac{1}{4}\)
\(=\frac{13}{15}-\frac{1}{4}\)
\(=\frac{37}{60}\)
