a) \(\frac{{125}}{{100}}\,{m^2}=\frac{{5}}{{4}}\,{m^2}=1\frac{{1}}{{4}}\,{m^2}\)
b) \(\frac{{218}}{{10000}}\,{m^2}=\frac{{109}}{{5000}}\,{m^2}\)
c) \(\frac{{240}}{{100}}\,{m^2}=\frac{{12}}{{5}}\,{m^2}=2\frac{{40}}{{100}}\,{m^2}\)
d) \(\frac{{34}}{{10000}}\,{m^2}=\frac{{17}}{{5000}}\,{m^2}\)
Nếu viết chúng theo đề-xi-mét vuông:
a) \(\frac{{125}}{1}\,d{m^2}\)
b) \(\frac{{218}}{{100}}\,{dm^2}=\frac{{109}}{{50}}\,{dm^2}=2\frac{{9}}{{50}}\,d{m^2}\)
c) \(\frac{{240}}{1}\,d{m^2}\)
d) \(\frac{{34}}{{100}}\,\,d{m^2}=\frac{{17}}{{50}}\,{dm^2}\)
