А )верно б)тоже верно

Answer 2

Solving the Equations

a) 6 2/3 - 1/3 * 1 + 3/4 + 1/4 - 6 > 0

Let's solve this step by step:

First, we simplify the mixed numbers: 6 2/3 = 20/3 3/4 = 0.75

Now, we can substitute these values into the equation: 20/3 - 1/3 * 1 + 0.75 + 1/4 - 6 > 0

Next, we perform the multiplication and addition: 20/3 - 1/3 + 0.75 + 1/4 - 6 > 0 (20/3 - 1/3) + 0.75 + 1/4 - 6 > 0 (19/3) + 0.75 + 1/4 - 6 > 0 (19/3) + 0.75 + 0.25 - 6 > 0 (19/3) + 1 - 6 > 0 (19/3) - 5 > 0 19/3 - 5 > 0 19/3 - 15/3 > 0 4/3 > 0

So, the result is 4/3 > 0.

b) (5 1/6 - 5 1/12) * 12 - 6 + 1/3 : 3 > 0

Let's solve this step by step:

First, we simplify the mixed numbers: 5 1/6 = 31/6 5 1/12 = 61/12

Now, we can substitute these values into the equation: (31/6 - 61/12) * 12 - 6 + 1/3 : 3 > 0

Next, we perform the subtraction and multiplication: ((31/6 - 61/12) * 12) - 6 + 1/3 : 3 > 0 ((31/6 - 61/12) * 12) - 6 + 1/3 : 3 > 0 ((62/12 - 61/12) * 12) - 6 + 1/3 : 3 > 0 ((1/12) * 12) - 6 + 1/3 : 3 > 0 1 - 6 + 1/3 : 3 > 0 -5 + 1/3 : 3 > 0 -5 + 1/9 > 0 -45/9 + 1/9 > 0 -44/9 > 0

So, the result is -44/9 > 0.

Conclusion

The results of the given inequalities are: a) 4/3 > 0 b) -44/9 > 0
