a)[tex] \frac{8}{10} - \frac{2}{10}= \frac{6}{10} [/tex]
b)[tex] \frac{36}{10} - \frac{30}{10}= \frac{6}{10} [/tex]
c)[tex] \frac{50}{10} - \frac{30}{10} - \frac{14}{10} = \frac{6}{10} [/tex]
Ex. 8
a)[tex] \frac{2}{4}- \frac{2}{8} = \frac{2}{8} = \frac{1}{4} [/tex]
b)[tex] \frac{75}{100} - \frac{50}{100} = \frac{25}{100} = \frac{1}{4} [/tex]
c)[tex] \frac{6}{4} - \frac{5}{4} = \frac{1}{4} [/tex]
d)[tex] \frac{6}{8}- \frac{2}{4} = \frac{2}{8}= \frac{1}{4} [/tex]
e)[tex] \frac{9}{12}- \frac{6}{12}= \frac{3}{12} = \frac{1}{4} [/tex]
