Question

6 2/3 - 1/3 * 1 3/4 + 1/4 - 6 больше 0 (3,08 - 2,16) : 8 - 0,17 * 3 меньше 0

Answer 1

Ну вроде бы так не знаю точно

Answer 2

Let's first simplify each expression step by step to determine if the given inequalities are true.

1. 6 2/3 - 1/3 * 1 3/4 + 1/4 - 6 > 0: First, let's convert all the mixed numbers to improper fractions. 6 2/3 = (6 * 3 + 2) / 3 = 20 / 3 1 3/4 = (1 * 4 + 3) / 4 = 7 / 4

Now, we can rewrite the expression as follows: (20 / 3) - (1/3) * (7/4) + (1/4) - 6 > 0

Next, let's perform the calculations: (20 / 3) - (7 / 12) + (1 / 4) - 6 > 0 [(80 - 7 + 3) / 12] - 6 > 0 (76 / 12) - 6 > 0 (19/3) - 6 > 0 (19/3) - (18/3) > 0 1/3 > 0

Since 1/3 is indeed greater than 0, the inequality is true.

2. (3.08 - 2.16) / 8 - 0.17 * 3 < 0: Let's calculate the expression step by step: (3.08 - 2.16) = 0.92 0.92 / 8 = 0.115

Next: 0.17 * 3 = 0.51

Now, the expression becomes: 0.115 - 0.51 < 0 -0.395 < 0

Since -0.395 is indeed less than 0, the inequality is true.

So, to summarize: 6 2/3 - 1/3 * 1 3/4 + 1/4 - 6 > 0 is true. (3.08 - 2.16) / 8 - 0.17 * 3 < 0 is true.
