Question

17:5=51:х пропорции​

Answer 1

$\frac{17}{5} = \frac{51}{x} \\ x = \frac{51 \times 5}{17} \\ x = \frac{3 \times 5}{1} \\ x = 15$

Answer 2

17:5=51:х

х=(51×5):17=15

Ответ: х=15

Answer 3

To solve for the value of "x" in the proportion $\frac{17}{5} = \frac{51}{x}$, you can use the concept of cross-multiplication:

Cross-multiplication states that if you have a proportion $\frac{a}{b} = \frac{c}{d}$, then $ad = bc$.

In your case: $\frac{17}{5} = \frac{51}{x}$

Cross-multiplying: $17x = 5 \cdot 51$

Now, divide both sides by 17 to solve for x: $x = \frac{5 \cdot 51}{17}$

Calculating the value: $x = \frac{255}{17}$ $x = 15$

So, the value of $x$ that satisfies the proportion is $x = 15$.
