Question

1) -0,5 + (1/4) + (1/4)= 2) -0,5 + (-0,5) + (-0,5)=

Answer 1

1)

-0,5 + (1/4) + (1/4) = -5/10 + 2/4 = -1/2 + 1/2 = 0,

2)

-0,5 + (-0,5) + (-0,5) =-0,5 - 0,5 - 0,5 = -3 * 0,5 = -1,5

Answer 2

1) 5/10+1/4+1/4= 1
2)1,5

Answer 3

Let's solve the two mathematical expressions step by step:

1. -0.5 + (1/4) + (1/4)

To add fractions, you need to find a common denominator. The common denominator for 4 and 4 is 4. Now, let's perform the addition:

-0.5 + (1/4) + (1/4) = -0.5 + 2/4 + 2/4

Now, add the fractions:

-0.5 + 2/4 + 2/4 = -0.5 + 4/4

Since 4/4 is equivalent to 1 (any number divided by itself is 1), we have:

-0.5 + 4/4 = -0.5 + 1

Finally, add the two numbers:

-0.5 + 1 = 0.5

So, the result of the first expression is 0.5.

2. -0.5 + (-0.5) + (-0.5)

Simply add the three numbers together:

-0.5 + (-0.5) + (-0.5) = -1.5

So, the result of the second expression is -1.5.
