a)

$2.5 = \frac{25}{10} = \frac{5}{2}$

b)

$- 3.75 = - \frac{375}{100} = - \frac{15}{4}$

c)

$- 0.12 = - \frac{12}{100} = - \frac{3}{25}$

d)

$0.(3) = \frac{3}{9} = \frac{1}{3}$

e)

$- 1.58(3) = - 1 \frac{583 - 58}{900} = - 1 \frac{525}{900} = - 1 \frac{7}{12} = - \frac{19}{12}$

f)

$1.0(54) = 1 \frac{54}{990} = 1 \frac{27}{495} = 1 \frac{3}{55} = \frac{58}{55}$

1.

$0.1(5) = \frac{15 - 1}{90} = \frac{14}{90} = \frac{7}{45}$

2.

$0.0(3) = \frac{3}{90} = \frac{1}{30}$

3.

$1.25(243) = 1\frac{25243 - 25}{99900} = 1 \frac{25218}{99900} = 1 \frac{12609}{49950} = 1 \frac{1401}{5550} = 1 \frac{467}{1850} = \frac{2317}{1850}$

4.

$0.7(23) = \frac{723 - 7}{990} = \frac{716}{990} = \frac{358}{495}$

5.

$2.32(4) = 2 \frac{324 - 32}{900} = 2 \frac{292}{900} = 2 \frac{146}{450} = 2 \frac{73}{225} = \frac{523}{225}$

6.

$0.321(5) = \frac{3215 - 321}{9000} = \frac{2894}{9000} = \frac{1447}{4500}$

7.

$0.24(5) = \frac{245 - 24}{900} = \frac{221}{900}$

8.

$6.4(25) = 6 \frac{425 - 4}{990} = 6 \frac{421}{990} = \frac{6361}{990}$
