We already have our first value 125 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 1125 = 25% × Y
STEP 2125 = 25/100× Y
STEP 3Y = 125 × 100/25
STEP 4Y = 125 × 100 ÷ 25
STEP 5Y = 500
Finally, we have found the value of Y which is 500 and that is our answer.
You can easily calculate 125 is 25 percent of what number by using any regular calculator, simply enter 125 × 100 ÷ 25 and you will get your answer which is 500

Question: Your friend has a bag of marbles, and he tells you that 25 percent of the marbles are red. If there are 125 red marbles. How many marbles does he have altogether?
Answer: 500 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 125.
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 125.
So step one is to just multiply that Part by 100.
125 × 100 = 12500
In step two, we take that 12500 and divide it by the "Percent", which we are told is 25.
So, 12500 divided by 25 = 500
And that means that the total number of marbles is 500.
Question: A high school marching band has 125 flute players, If 25 percent of the band members play the flute, then how many members are in the band?
Answer: There are 500 members in the band.
How To: The smaller "Part" in this problem is 125 since there are 125 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.
125 × 100 = 12500
For step two, we divide that 12500 by the "Percent", which is 25.
12500 divided by 25 equals 500
That means that the total number of band members is 500.
Step 1: Let's assume the unknown value is Y
Step 2: First writing it as: 100% / Y = 25% / 125
Step 3: Drop the percentage marks to simplify your calculations: 100 / Y = 25 / 125
Step 4: Multiply both sides by Y to move Y on the right side of the equation: 100 = ( 25 / 125 ) 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 500 = Y
This leaves us with our final answer: 125 is 25 percent of 500
