Question

(-2 1/8)*(-1 29/51)+(-1 23/42)*3 1/13-(-4 2/3)

Answer 1

$1) - 2 frac{1}{8} times ( - 1 frac{29}{51} ) = \ frac{17}{8} times frac{80}{51} = frac{10}{3} = 3 frac{1}{3}$

$2) - 1 frac{23}{42} times 3 frac{1}{13} = - frac{65}{42} times frac{40}{13} = \ - frac{5 times 20}{21} = - frac{100}{21} = - 4 frac{16}{21}$

$3)3 frac{1}{3} - 4 frac{16}{21} = 3 frac{7}{21} - 4 frac{16}{21} = \ - 1 frac{9}{21} = - 1 frac{3}{7}$

$4) - 1 frac{3}{7} - ( - 4 frac{2}{3} ) = \ - 1 frac{9}{21} + 4 frac{14}{21} = 3 frac{5}{21}$
