Question

-(3,5*4/7-3.5:1 целая3/4)+(1,02-100)=?

Answer 1

(35/10*4/7+35/10*4/7)-98,98=2+2-98,98=-94,98

Answer 2

To solve this expression, we'll need to follow the order of operations, which is commonly remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Let's break down the expression step by step:

1. First, we need to simplify the expression inside the parentheses:

   • 5*4/7 = 20/7
   • 3.5:1 = 3.5 (since dividing by 1 doesn't change the value)
   • 20/7 - 3.5 = 20/7 - 24/7 = -4/7 So the expression inside the parentheses simplifies to -4/7.

2. Now we can substitute that value back into the original expression: -(3,5*4/7-3.5:1 целая3/4)+(1,02-100) becomes -( -4/7 ) + (1.02 - 100)

3. Next, we need to simplify the addition and subtraction in this expression: -(-4/7) = 4/7 (since two negatives cancel each other out) 1.02 - 100 = -98.98

4. Finally, we add these two values together: 4/7 + (-98.98) = -98.58

Therefore, the final answer is -98.58.
