Answer:
1.[tex]\bold{\frac{2}{5} - \frac{2}{10} = \frac{1}{5} }[/tex]
Solution:
[tex]\bold{(\frac{2}{5} \times \frac{2}{2})( \frac{2}{10} \times \frac{1}{1} )}[/tex]
[tex]\bold{\frac{4}{10} - \frac{2}{10}}[/tex]
[tex]\bold{ \frac{4 - 2}{10} = \frac{2}{10} }[/tex]
[tex]\bold{\frac{2 \div 2}{10 \div 2} = \frac{1}{5} }[/tex]

2.[tex]\bold{ \frac{3}{6} - \frac{5}{12} = \frac{1}{2} }[/tex]
Solution:
[tex]\bold{(\frac{3}{6} \times \frac{2}{2})( \frac{5}{12} \times \frac{1}{1} )}[/tex]
[tex]\bold{ \frac{6}{12} - \frac{5}{12}}[/tex]
[tex]\bold{ \frac{6 - 5}{12} = \frac{1}{12} }[/tex]
_________________________
3.[tex]\bold{ \frac{7}{15} - \frac{2}{5} = \frac{1}{15} }[/tex]
Solution:
[tex]\bold{(\frac{7}{15} \times \frac{1}{1})( \frac{2}{5} \times \frac{3}{3} )}[/tex]
[tex]\bold{ \frac{7}{15} - \frac{6}{15}}[/tex]
[tex]\bold{\frac{7 - 6}{15} = \frac{1}{5} }[/tex]
