Solve the Equation: Finding the Missing Factor in 61 × ? = 0

$61\times?=0$

To solve this problem, let's delve into the properties of multiplication:

• Step 1: Identify the equation we're solving, $61 \times ? = 0$.
• Step 2: Recall a key mathematical property: any number multiplied by zero equals zero. This is known as the multiplication property of zero.
• Step 3: Based on this property, $?$ must be zero because multiplying 61, or any number, by zero results in zero.

Given the understanding of the property above, the unknown number, $?$, that satisfies the equation is zero.

The correct answer, according to the choices given, is choice 4, where $? = 0$.

Therefore, the solution to the problem is $? = 0$.
