Answer 1

Відповідь:перше 4/7 друге  -1\6

Покрокове пояснення:

перше 1/7 * 2 *2 = 4/7

друге 1/3 * (-1/2) = -1/6

Answer 2

To calculate the expression (-3/7) * (-2/3) * 2 * (1/3) * (-2.25), you need to follow the order of operations (also known as PEMDAS/BODMAS). Here's the step-by-step solution:

1. Start by multiplying the numerators and denominators across the expression: (-3/7) * (-2/3) * 2 * (1/3) * (-2.25) = (-3 * -2 * 2 * 1 * -2.25) / (7 * 3 * 3)

2. Simplify the multiplication: (-3 * -2 * 2 * 1 * -2.25) = 27

3. Simplify the denominators: (7 * 3 * 3) = 63

4. Substitute the simplified values back into the expression: (-3/7) * (-2/3) * 2 * (1/3) * (-2.25) = 27/63

5. Reduce the fraction if possible: 27/63 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 9: 27/63 = (27 ÷ 9) / (63 ÷ 9) = 3/7

Therefore, the value of the expression (-3/7) * (-2/3) * 2 * (1/3) * (-2.25) is 3/7.
