0,5:1,3=
64,45:0,18=
1,24:2,7=
0,632:1,8=

Answer 1

12,4:37= $\frac{124}{10} : \frac{37}{1} = \frac{124}{10} * \frac{1}{37} = \frac{124}{370} = \frac{62}{135}$
0,9:2,2= $= \frac{9}{10} : \frac{22}{10}= \frac{9}{10} * \frac{10}{22} = \frac{90}{220} = \frac{9}{22}$
0,5:1,3=$\frac{5}{10} : \frac{13}{10} = \frac{5}{10} * \frac{10}{13} = \frac{50}{130} = \frac{5}{13}$
64,45:0,18=$\frac{6445}{100} : \frac{18}{100} = \frac{6445}{100} * \frac{100}{18} = \frac{6445}{18}$
1,24:2,7=$\frac{124}{100} : \frac{27}{10} = \frac{124}{100} * \frac{10}{27}= \frac{124}{270} = \frac{62}{135}$
0,632:1,8=$\frac{632}{1000} : \frac{18}{10} = \frac{632}{1000} * \frac{10}{18} = \frac{632}{1800} = \frac{79}{225}$
