Solve the Decimal Equation: Finding the Missing Value in 5.2:?=0.52

To find the value of '?', we'll set up the equation based on the division of numbers:

Given that $5.2 \div ? = 0.52$, we can rewrite this equation as:

$5.2 = 0.52 \times ?$

To isolate the '?', we divide both sides of the equation by 0.52:

$? = \frac{5.2}{0.52}$

Calculating this division gives us:

$? = 10$

This means when 5.2 is divided by 10, the result is 0.52, confirming that '? = 10' is correct.

Therefore, the solution to the problem is $10$.
