Question

600 + 400 : 200 : 100 = 800 раставить скобки.

Answer 1

600+ 400 : ( 200 : 100 ) = 800

Answer 2

600 + 400 : (200 : 100) = 600 + 400 : 2 = 600 + 200 = 800

Answer 3

To clarify the expression, you provided: 600 + 400 ÷ 200 : 100 = 800

To correctly place the parentheses, let's break down the expression using the order of operations (also known as PEMDAS/BODMAS):

1. Parentheses
2. Exponents (i.e., powers and square roots, etc.)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Applying these rules, we can reorganize the expression as follows:

600 + (400 ÷ 200) : 100 = 800

Now, we can evaluate the expression within the parentheses first:

400 ÷ 200 = 2

Replacing the evaluated expression back into the original equation:

600 + 2 : 100 = 800

Next, we perform the division operation:

2 ÷ 100 = 0.02

Substituting the result back into the equation:

600 + 0.02 = 800

Finally, we can simplify the equation:

600.02 = 800

So, the correct placement of parentheses in the expression 600 + 400 : 200 : 100 to obtain the result of 800 is:

600 + (400 ÷ 200) : 100 = 800
