Answer 1

$0.13 = \frac{13}{100}$

$1.3 = \frac{13}{10}$

$1.013 = \frac{1013}{1000}$

$1.03 = \frac{103}{100}$

$2.25 = \frac{225}{100} = \frac{45}{20} = \frac{9}{4}$

$1.08 = \frac{108}{100} = \frac{54}{50} = \frac{27}{25}$

$5.075 = \frac{5075}{1000} = \frac{1015}{200} = \frac{203}{40}$

$0.0004 = \frac{4}{10000} = \frac{2}{5000} = \frac{1}{2500}$
