Solve the Ratio Equation: Finding the Missing Value in 50:? = 50

To solve this problem, we'll follow these steps:

• Step 1: Identify that this is a division problem, with the result already given as 50.
• Step 2: Apply the identity property of division, which states that dividing any number by 1 results in the number itself.
• Step 3: Recognize that since $\frac{50}{x} = 50$, the only value for $x$ that makes this true is 1.

Now, let's work through each step:
Step 1: We are given $50 : ? = 50$, which is equivalent to finding a number $x$ such that $\frac{50}{x} = 50$.
Step 2: According to division properties, the only number we can divide 50 by to still get 50 is 1.
Step 3: Therefore, the unknown divisor must be 1.

Hence, the solution to the problem is that the missing number is $x = 1$.
