Question

Пример 5класс
(6 1/4-4 1/8)*4+3 1/3:2 1/2

Answer 1

$(6 frac{1}{4} - 4 frac{1}{8} ) times 4 + 3 frac{1}{3} div 2 frac{1}{2} = ( frac{25}{4} - frac{33}{8} ) times 4 + frac{10}{3} div frac{5}{2} = frac{59}{6}$



$1) : frac{25}{4} - frac{33}{8} = frac{25 times 2}{4 times 2} - frac{33}{8} = frac{50}{8} - frac{33}{8} = frac{17}{8}$



$2) : frac{17}{8} times 4 = frac{17 times 4}{8} = frac{17 times 1}{2} = frac{17}{2}$


$3) : frac{10}{3} div frac{5}{2} = frac{10}{3} times frac{2}{5} = frac{10 times 2}{3 times 5} = frac{2 times 2}{3 times 1} = frac{4}{3}$

$4) : frac{17}{2} + frac{4}{3} = frac{17 times 3}{2 times 3} + frac{4 times 2}{3 times 2} = frac{51}{6} + frac{8}{6} = frac{59}{6} .$

$otvet : frac{59}{6}$
