Answer 1

$1)a)12.5 = \frac{125}{10} = \frac{25}{2}$

$b)1.25 = \frac{125}{100} = \frac{25}{20} = \frac{5}{4}$

$c)0.125 = \frac{125}{1000} = \frac{25}{200} = \frac{5}{40} = \frac{1}{8}$

$d)22.75 = \frac{2275}{100} = \frac{455}{20} = \frac{91}{4}$

$e)0.2 = \frac{2}{10} = \frac{1}{5}$

$f)13.1 = \frac{131}{10}$

$g)16.9 = \frac{169}{10}$

$h)7.1 = \frac{71}{10}$

$i)62.5 = \frac{625}{10} = \frac{125}{2}$

$j)0.0625 = \frac{625}{10000} = \frac{125}{2000} = \frac{25}{400} = \frac{5}{80} = \frac{1}{16}$

$k)0.8 = \frac{8}{10} = \frac{4}{5}$

$2)a)273.6 = \frac{2736}{10} = \frac{1368}{5}$

$b)1405.25 = \frac{140525}{1000} = \frac{28105}{200}=\frac{5621}{40}$

$c)46.64 = \frac{4664}{100} = \frac{2332}{50}$

$d)103.08 = \frac{10308}{100} = \frac{5154}{50} = \frac{2577}{25}$

$e)79.125 = \frac{79125}{1000} = \frac{15825}{200} = \frac{3165}{40} = \frac{633}{8}$

$f)13.1 = \frac{131}{10}$

$g)0.0064 = \frac{64}{10000} = \frac{32}{5000} = \frac{16}{2500} = \frac{8}{1250} = \frac{4}{625}$

$h)1.9 = \frac{19}{10}$

$i)1.99 = \frac{199}{100}$

$j)1.999 = \frac{1999}{1000}$

$k)0.99 = \frac{99}{100}$

$l)7.05 = \frac{705}{100} = \frac{141}{20}$

$m)6.25 = \frac{625}{100} = \frac{125}{20} = \frac{25}{4}$

$n)0.500 = \frac{500}{1000} = \frac{1}{2}$
