We already have our first value 25 and the second value 25. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 125 = 25% × Y
STEP 225 = 25/100× Y
STEP 3Y = 25 × 100/25
STEP 4Y = 25 × 100 ÷ 25
STEP 5Y = 100
Finally, we have found the value of Y which is 100 and that is our answer.
You can easily calculate 25 is 25 percent of what number by using any regular calculator, simply enter 25 × 100 ÷ 25 and you will get your answer which is 100

Question: Your friend has a bag of marbles, and he tells you that 25 percent of the marbles are red. If there are 25 red marbles. How many marbles does he have altogether?
Answer: 100 marbles.
How To: In this problem, we know that the Percent is 25, and we are also told that the Part of the marbles is red, so we know that the Part is 25.
So, that means that it must be the Total that's missing. Here is the way to figure out what the Total is:
Part/Total = Percent/100
By using a simple algebra we can re-arrange our Percent equation like this:
Part × 100/Percent = Total
If we take the "Part" and multiply it by 100, and then we divide that by the "Percent", we will get the "Total".
Let's try it out on our problem about the marbles, that's very simple and it's just two steps! We know that the "Part" (red marbles) is 25.
So step one is to just multiply that Part by 100.
25 × 100 = 2500
In step two, we take that 2500 and divide it by the "Percent", which we are told is 25.
So, 2500 divided by 25 = 100
And that means that the total number of marbles is 100.
Question: A high school marching band has 25 flute players, If 25 percent of the band members play the flute, then how many members are in the band?
Answer: There are 100 members in the band.
How To: The smaller "Part" in this problem is 25 since there are 25 flute players and we are told that they make up 25 percent of the band, so the "Percent" is 25.
Again, it's the "Total" that's missing here, and to find it, we just need to follow our 2 step procedure as the previous problem.
For step one, we multiply the "Part" by 100.
25 × 100 = 2500
For step two, we divide that 2500 by the "Percent", which is 25.
2500 divided by 25 equals 100
That means that the total number of band members is 100.
Step 1: Let's assume the unknown value is Y
Step 2: First writing it as: 100% / Y = 25% / 25
Step 3: Drop the percentage marks to simplify your calculations: 100 / Y = 25 / 25
Step 4: Multiply both sides by Y to move Y on the right side of the equation: 100 = ( 25 / 25 ) Y
Step 5: Simplifying the right side, we get: 100 = 25 Y
Step 6: Dividing both sides of the equation by 25, we will arrive at 100 = Y
This leaves us with our final answer: 25 is 25 percent of 100
