Solve the Division Equation: Finding the Number That Makes ?÷70 = 0

$?:70=0$

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

• Step 1: Interpret the given equation: $?:70 = 0$.
• Step 2: Recognize that in division $\frac{a}{b} = 0$, the numerator $a$ must be zero.
• Step 3: Conclude that the unknown $?$ must equal zero because only $0$ divided by $70$ results in $0$.

Now, let's work through each step:
Step 1: The problem involves an equation where $\frac{?}{70} = 0$.
Step 2: We know that the result of a division being zero ($\frac{?}{70} = 0$) implies that the numerator $?$ must itself be zero — since any nonzero numerator would yield a nonzero quotient.
Step 3: Hence, we conclude that the unknown $? = 0$ because the only value that satisfies the division condition of $0$ is if the numerator itself is zero.

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