Final answer:
To solve the proportion 5/7 = x/35, cross multiply by multiplying 5 * 35 and 7 * x, then simplify and solve for x by dividing both sides by 7. The answer is x = 25.
Step-by-step explanation:
To solve the proportion 5/7 = x/35, we can cross multiply. This means multiplying the numerator (top) of one fraction by the denominator (bottom) of the other fraction. So, 5 * 35 = 7 * x. Simplifying, we get 175 = 7x. To solve for x, we divide both sides of the equation by 7. Therefore, x = 25.
