Fill in the missing values (?):
25+?:?=25
To solve this problem, we need to find the missing values that satisfy the equation 25+?:?=25. Let's analyze each operation involved in this expression:
- Addition: The sum of any number and 0 is the original number, i.e., a+0=a.
- Division: A number divided by 1 remains unchanged, i.e., a:1=a.
Let’s apply these properties step by step.
- Step 1: Assume the first missing value is 0. This transforms the equation to 25+0:?=25.
- Step 2: Simplifying, we are left with 25+(0:?)=25.
- Step 3: The term 0:? results in 0 for any nonzero divisor. Therefore, we effectively have 25+0=25, which is true for any value of the second placeholder as 1 (since 0:4=0 also holds).
After analyzing, let's verify the given choices. The choice 0,4 fits the criteria:
- The first value, 0, ensures the sum does not change (25+0=25).
- The second value, 4, ensures division results in zero which corresponds with 0.
Thus, the missing values are indeed correctly filled by 0,4.
Therefore, the solution to the problem is:
0,4
