Question

А) (7-15)×2+5= б) 16×(5\16-3\8+1\4)= в) (5,25-1\4):0,2=

Answer 1

Ответ:

А) -11

б) 3

В) 25

Пошаговое объяснение:

(7-15)*2+5=-8*2+5=-16+5=-11

16*(5\16-3\8+1\4)=16*(5/16-6/16+4/16)=16*3/16=3

(5,25-1\4):0,2=5*5=25

Answer 2

а) (7-15)×2+5 = (-8) × 2 + 5 = -16 + 5 = -11

б) 16 × (5/16 - 3/8 + 1/4) = 16 × (10/32 - 12/32 + 8/32) = 16 × (6/32) = 3

в) (5.25 - 1/4) / 0.2 = (21/4 - 1/4) / 0.2 = (20/4) / 0.2 = 5 / 0.2 = 25
