810÷(3×30)+250÷(20+30)

Answer 1

Ответ:

1) 3200;

2) 14

Пошаговое объяснение:

1) 2199 + (25 × 9 × 4) + 101 = 2199 + 900 + 101 = 3200

2)

$displaystylefrac{810}{3*30} +frac{250}{20+30} =frac{810}{90} +frac{250}{50} =9+5=14$

Answer 2

$2199 + (25 times 9 times 4) + 101 = (25 times 9 times 4) = 900 + 2199 + 101 = 3200 \ 810 div (3 times 30) + 250 div (20 + 30) = (3 times 30) = 90(20 + 30) = 50 : 810 div 90 = 9 : 250 div 50 = 5 : 9 + 5 = 14$
