Answer 2

Ответ:

2/7

Пошаговое объяснение:

$\displaystyle \: x : \frac{5}{6} = \frac{12}{35} \\ \\ \frac{x}{ \dfrac{5}{6} } = \frac{12}{35} \\ \\ 35x = \frac{5}{6} \cdot \frac{12}{1} \\ \\ 35x = 5 \cdot2 \\ \\ 35x = 10 \\ \\ x = \frac{10}{35} \\ \\ x = \frac{2}{7}$

Answer 3

To determine if the equation 5/6 = 12/35 is true or false, we can cross-multiply and compare the results.

Cross-multiplying means multiplying the numerator of the first fraction with the denominator of the second fraction and vice versa. Let's do that:

5 × 35 = 175 6 × 12 = 72

Comparing the results, we can see that 175 is not equal to 72. Therefore, the equation 5/6 = 12/35 is false.
