Answer 1

$a) \frac{1}{5} = \frac{1 \times 4}{5 \times 4} = \frac{4}{20}$

$b) \frac{4}{7} = \frac{4 \times 4}{7 \times 4} = \frac{16}{28}$

$c) \frac{2}{25} = \frac{2 \times 4}{25 \times 4} = \frac{8}{100}$

$d) \frac{29}{10} = \frac{29 \times 4}{10 \times 4} = \frac{116}{40}$

$e) \frac{17}{50} = \frac{17 \times 4}{50 \times 4} = \frac{68}{200}$

$f) \frac{35}{12} = \frac{35 \times 4}{12 \times 4} = \frac{140}{48}$
