Solve Division Equation: Finding the Missing Divisor in 60 ÷ ? = 60

$60:?=60$

To solve this problem, we need to determine what number $(?)$ satisfies the equation $60:?=60$.

Consider the given equation:
$\frac{60}{?} = 60$

According to the properties of division, dividing a number by 1 returns the number itself:
$\frac{a}{1} = a$ for any number $a$.

Applying this principle to our equation:
- If $60 \div ? = 60$, then $?$ must be 1, because:
$\frac{60}{1} = 60$

Therefore, the number that satisfies the equation is $1$.

Thus, the correct choice is:

• $1$
