Answer 1

b)

$2.(5) = \frac{25 - 2}{9} = \frac{23}{9}$

$13.(7) = \frac{137 - 13}{9} = \frac{124}{9}$

$125.(8) = \frac{1258 - 125}{9} = \frac{1133}{9}$

$0.(29) = \frac{29}{99}$

$4.(37) = \frac{437 - 4}{99} = \frac{433}{99}$

$125.(106) = \frac{125106 - 125}{999} = \frac{119981}{999}$

$29.(471) = \frac{29471 - 29}{999} = \frac{29442}{999}$

c)

$0.2(7) = \frac{27 - 2}{90} = \frac{25}{90 } = \frac{5}{18}$

$4.6(5) = \frac{465 - 46}{90} = \frac{419}{90}$

$8.23(7) = \frac{8237 - 823}{900} = \frac{7414}{900}$

$16.14(35) = \frac{161435 - 1614}{9900} = \frac{159821}{9900}$

$200.79(125) = \frac{20079125 - 20079}{99900} = \frac{20059046}{999000}$
