Question

Вычислите
(13 2/3 × 2 1/7-12 2/3×2 1/7):1 1/14×3 1/3+1/3
Помогите срочноооо

Answer 1

1)
$13 frac{2}{3} times 2 frac{1}{7} = frac{41}{3} times frac{15}{7} = frac{41 times 5}{7} = \ = frac{205}{7} = 29 frac{2}{7}$
2)
$12 frac{2}{3} times 2 frac{1}{7} = frac{38}{3} times frac{15}{7} = frac{38 times 5}{7} = \ = frac{190}{7} = 27 frac{1}{7}$
3)
$29 frac{2}{7} - 27 frac{1}{7} = 2 frac{1}{7}$
4)
$2 frac{1}{7} div 1 frac{1}{14} = frac{15}{7} times frac{14}{15} = 2$
5)
$2 times 3 frac{1}{3} = 2 times frac{10}{3} = frac{20}{3} = 6 frac{2}{3}$
6)
$6 frac{2}{3} + frac{1}{3} = 6 frac{3}{3} = 7$
