Answer 2

To solve the proportion, we can set up a cross-multiplication equation. In this case, the proportion is:

3:15 = 7:x

Cross-multiplying, we get:

3x = 7 * 15

Simplifying the right side:

3x = 105

Now, to isolate x, we divide both sides of the equation by 3:

x = 105/3

Calculating the right side:

x = 35

Therefore, the value of x that satisfies the proportion 3:15 = 7:x is 35.
