Answer:
The smallest number that must be added to 25 to make it a multiple of 4 is 3.
Explanation:
To make 25 a multiple of 4, you need to find the smallest number that, when added to 25, results in a multiple of 4.
Let's call this number "x." So, you have:
25 + x
To make this a multiple of 4, it should be divisible by 4 without a remainder. In other words, 25 + x should be a multiple of 4, which means:
(25 + x) % 4 = 0
Now, let's solve for x:
(25 + x) % 4 = 0
We can rewrite this equation as:
x % 4 = 4 - (25 % 4)
Now, calculate:
25 % 4 = 1
So,
x % 4 = 4 - 1
x % 4 = 3
