Answer 1

a) 1 / 3 + 2 / 9 + 4 / 3 > mmc = 9

$\frac{1}{3} + \frac{2}{9} + \frac{4}{3} > \frac{9}{9} + \frac{2}{9} + \frac{12}{9} \\ \\ \frac{9 + 2 + 12}{9} = \frac{23}{9}$

b)

$\frac{1}{10} + \frac{7}{10} + \frac{3}{10} > \frac{1 + 7 + 3}{10} = \frac{11}{10}$

c) 7 / 15 + 3 / 15 - 1 / 10 > mmc = 30

$\frac{7}{15} + \frac{3}{15} - \frac{1}{10} > \frac{14}{30} + \frac{6}{30} - \frac{3}{30} \\ \\ \frac{14 + 6 - 3}{30} = \frac{17}{30}$

d)

$\frac{7}{8} + \frac{2}{8} + \frac{1}{8} > \frac{7 + 2 + 1}{8} = \frac{10 {}^{ \div 2} }{8 {}^{ \div 2} } = \frac{5}{4}$
