Question

-1,2:(1,5-1,8)+0,35:(0,83-0,9)

Answer 1

Ответ:-4,637

Пошаговое объяснение:

-1,2:(1,5-1,8)+0,35:(0,83-0,9)=-1,21*(-0,3)+7/20/(-0,07)=0,363+7/20/(7/100)=0,363-7/20*100/7=0,363-5=-4,637

Answer 2

To evaluate the expression, let's follow the order of operations (PEMDAS):

P: Parentheses first E: Exponents (none in this expression) MD: Multiplication and Division (from left to right) AS: Addition and Subtraction (from left to right)

Given expression: -1,2 * (1,5 - 1,8) + 0,35 * (0,83 - 0,9)

Step 1: Parentheses 1,5 - 1,8 = -0,3 0,83 - 0,9 = -0,07

Step 2: Multiplication and Division -1,2 * (-0,3) = 0,36 0,35 * (-0,07) = -0,0245

Step 3: Addition and Subtraction 0,36 + (-0,0245) = 0,3355

Therefore, the result of the expression is approximately 0.3355.
