Question

Помогите пожалуйста вычислить
А) 9/14-3/7+5/28
Б)7/12-5/6+13/24
В)13/18-29/45+8/15
Г)9/16+7/24-3/8

Answer 1

$frac{9}{14} - frac{3}{7} + frac{5}{28} = frac{9-6}{14} + frac{5}{28} = frac{6+5}{28} = frac{11}{28}$
$frac{7}{12} - frac{5}{6} + frac{13}{24} = frac{7-10}{12} + frac{13}{24} = frac{-6+13}{24} = frac{7}{27}$
$frac{13}{18} - frac{29}{45} + frac{8}{15} = frac{13}{18} - frac{5}{45} = frac{13}{18} - frac{1}{9} = frac{13-2}{18} = frac{11}{18}$
$frac{9}{16}+ frac{7}{24} - frac{3}{8} = frac{9}{16} + frac{7-9}{24} = frac{9}{16} - frac{2}{24} = frac{9}{16} - frac{1}{12} = frac{108-16}{192} = frac{92}{192} = frac{23}{48}$
