Question

-5/7+4/7=5/12+(-1/12)=(-1/6)+1=5/16+(-1/16)=(-4)+3 1/2=​

Answer 1

Ответ:

- 1/7

6/12 = 1/2

5/6

4/16 = 1/4

-1/2

Answer 2

Ответ:

1) 1/7

2) 1/3

3) 5/6

4) 1/4

5) (-5/2) или 2.5

Пошаговое объяснение:

1) 4/7-5/7=(4-5)/7=-1/7

2) 5/12+(- 1/12)= 5-1/12=4/12=1*4/3*4=1/3

3) 1-1/6=6/6-1/6=5/6

4) 5-1/16=4/16 сокращаем= 1/4

5) (-4)+3 1/2=​ 3*1/2=(-4)+2/3=(-8/2)+3/2=(-5/2)=-2.5

Answer 3

Let's break down the calculation step by step:

1. Start with the expression -5/7 + 4/7: -5/7 + 4/7 = (-5 + 4)/7 = -1/7

2. Next, add 5/12 to -1/12: 5/12 + (-1/12) = (5 - 1)/12 = 4/12 = 1/3

3. Now, add -1/6 to 1/3: -1/6 + 1/3 = (-1/6 + 2/6) = 1/6

4. Continue by adding 5/16 to -1/16: 5/16 + (-1/16) = (5 - 1)/16 = 4/16 = 1/4

5. Finally, add 3 1/2 to -1/4: 3 1/2 - 1/4 = 7/2 - 1/4 = (14/4) - (1/4) = 13/4

So, the final result is 13/4, which can also be expressed as a mixed number as 3 1/4.
