Question

- 1/3+1/2= -5/18+(-1/24)= -3/8-5/8= 2/5-4/5= -2/3-(-1/3)=

Answer 1

Ответ:

Пошаговое объяснение:

-1/3+1/2=-2/6+3/6=1/6

-5/18+(-1/24)=-20/72-3/72=-23/72

-3/8-5/8==-8/8=-1

2/5-4/5==-2/5

-2/3-(-1/3)==-2/3+1/3=-1/3

Answer 2

Let's solve each of these arithmetic expressions step by step:

1. 1/3 + 1/2: To add these fractions, we need to find a common denominator, which is 6. So: 1/3 + 1/2 = (2/2 * 1/3) + (3/3 * 1/2) = 2/6 + 3/6 = 5/6.

2. -5/18 + (-1/24): Again, find the common denominator, which is 72: -5/18 + (-1/24) = (-4/24 * -5/18) + (-3/18 * -1/24) = 20/72 + 3/72 = 23/72.

3. -3/8 - 5/8: Since the denominators are the same, you can directly subtract the numerators: -3/8 - 5/8 = (-3 - 5)/8 = -8/8 = -1.

4. 2/5 - 4/5: As the denominators are the same, simply subtract the numerators: 2/5 - 4/5 = (2 - 4)/5 = -2/5.

5. -2/3 - (-1/3): Remember that subtracting a negative fraction is the same as adding the positive fraction: -2/3 - (-1/3) = -2/3 + 1/3 = (-2 + 1)/3 = -1/3.

So, the results are as follows:

1. 1/3 + 1/2 = 5/6.
2. -5/18 + (-1/24) = 23/72.
3. -3/8 - 5/8 = -1.
4. 2/5 - 4/5 = -2/5.
5. -2/3 - (-1/3) = -1/3.
