Answer:
C. 15
Explanation:
To solve the proportion x/25 = 3/5, we can cross-multiply.
Step 1: Multiply the numerator of the first fraction (x) by the denominator of the second fraction (5), and multiply the numerator of the second fraction (3) by the denominator of the first fraction (25).
(x * 5) = (3 * 25)
Step 2: Simplify both sides of the equation.
5x = 75
Step 3: Divide both sides of the equation by 5 to isolate x.
5x/5 = 75/5
x = 15
Therefore, the value of x is 15. So, the answer is C. 15.
