Question

(-1 1/3)2 • (-0,375) + 1 1/3

Answer 1

Ответ: 2 1/3.

Пошаговое объяснение:

(-1 1/3)*2*(-0,375) + 1 1/3 =  4/3*2*375/1000 +1  1/3 = 1 + 1  1/3 =2 1/3.

Answer 2

Let's break down the expression step by step:

1. (-1 1/3)^2: First, we need to square (-1 1/3). To do that, convert it to an improper fraction: -1 1/3 = -4/3

   Now, square it: (-4/3)^2 = 16/9

2. Next, multiply the result by (-0.375): (16/9) * (-0.375)

To multiply fractions, multiply the numerators together and the denominators together: (16 * -0.375) / 9

Now, calculate the numerator: 16 * -0.375 = -6

So, the expression becomes: (-6) / 9

3. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3: (-6 / 3) / (9 / 3) = -2 / 3

4. Finally, add 1 1/3 to the result: -2/3 + 1 1/3

To add fractions with different denominators, you need to find a common denominator, which in this case is 3. So, convert 1 1/3 to an improper fraction with a denominator of 3: 1 1/3 = (3 * 1 + 1) / 3 = 4/3

Now, you can add the fractions: (-2/3) + (4/3)

To add fractions, you simply add the numerators together when the denominators are the same: (-2/3) + (4/3) = (4 - 2) / 3 = 2/3

So, the final result is 2/3.
