Tìm một số biết \(\dfrac{3}{5}\% \) của nó bằng $0,3.$

\(\dfrac{{2\dfrac{{11}}{{12}}}}{{6\dfrac{1}{8}}} = \dfrac{{10}}{{21}}\)

\(66\dfrac{2}{3}\%  = \dfrac{{11}}{{25}}\)

\(0,72:2,7 = \dfrac{4}{{15}}\)

\(0,075:5\%  = \dfrac{3}{2}\)

\( - \dfrac{{31}}{{24}} <  - 1\dfrac{1}{{12}} < \dfrac{{12}}{{100}} < 5\dfrac{1}{2} < 23\% \)           

\( - \dfrac{{31}}{{24}} <  - 1\dfrac{1}{{12}} < 23\%  < \dfrac{{12}}{{100}} < 5\dfrac{1}{2}\)

\( - \dfrac{{31}}{{24}} <  - 1\dfrac{1}{{12}} < \dfrac{{12}}{{100}} < 23\%  < 5\dfrac{1}{2}\)             

\( - 1\dfrac{1}{{12}} <  - \dfrac{{31}}{{24}} < \dfrac{{12}}{{100}} < 23\%  < 5\dfrac{1}{2}\)
