\(\frac{3}{4}\,\, = \,\,\frac{{75}}{{100}}\,\, = \,\,0,75\) | \(\frac{{98}}{{200}}\,\, = \,\,\frac{{49}}{{100}}\,\, = \,\,0,49\) | \(\frac{{63}}{{70}}\,\, = \,\,\frac{9}{{10}}\,\, = 0,9\) |
\[\frac{1}{8}\,\, = \,\,\frac{{125}}{{1\,\,000}}\,\, = \,\,0,125\] | \[\frac{{499}}{{500}}\,\, = \,\,\frac{{998}}{{1\,\,000}}\,\, = \,\,0,998\] | \(\frac{{124}}{{125}}\,\, = \,\,\frac{{992}}{{1\;000}}\,\, = 0,992\) |
\(\frac{7}{{20}}\,\, = \,\,\frac{{35}}{{100}}\,\, = \,\,0,35\) | \(\frac{{19}}{{250}}\,\, = \,\,\frac{{76}}{{1\,\,000}}\,\, = \,\,0,076\) | \(\frac{{56}}{{200}}\,\, = \,\,\frac{{28}}{{100}}\,\, = \,\,0,28\) |
