Làm theo mẫu:
\(\frac{{43}}{5} = \frac{{86}}{{10}} = 8,6\)
\(\frac{2}{{25}} = ...\)
\(\frac{{111}}{{125}} = ...\)
\(\frac{{23}}{8} = ...\)
\(\frac{{76}}{4} = ...\)
\(\frac{{42}}{{25}} = ...\)
\(\frac{{370}}{{50}} = ...\).
Trả lời
Ta có:
\(\frac{2}{{25}} = \frac{8}{{100}} = 0,08\)
\(\frac{{111}}{{125}} = \frac{{888}}{{1000}} = 0,888\)
\(\frac{{23}}{8} = \frac{{2875}}{{1000}} = 2,875\)
\(\frac{{76}}{4} = \frac{{1900}}{{100}} = 19\)
\(\frac{{42}}{{25}} = \frac{{168}}{{100}} = 1,68\)
\(\frac{{370}}{{50}} = \frac{{740}}{{100}} = 7,4.\)
