We already have our first value 35 and the second value 80. 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 135 = 80% × Y
STEP 235 = 80/100× Y
Multiplying both sides by 100 and dividing both sides of the equation by 80 we will arrive at:
STEP 3Y = 35 × 100/80
STEP 4Y = 35 × 100 ÷ 80
STEP 5Y = 43.75
Finally, we have found the value of Y which is 43.75 and that is our answer.
You can easily calculate 35 is 80 percent of what number by using any regular calculator, simply enter 35 × 100 ÷ 80 and you will get your answer which is 43.75

Question: Your friend has a bag of marbles, and he tells you that 80 percent of the marbles are red. If there are 35 red marbles. How many marbles does he have altogether?
Answer: 43.75 marbles.
How To: In this problem, we know that the Percent is 80, and we are also told that the Part of the marbles is red, so we know that the Part is 35.
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 35.
So step one is to just multiply that Part by 100.
35 × 100 = 3500
In step two, we take that 3500 and divide it by the "Percent", which we are told is 80.
So, 3500 divided by 80 = 43.75
And that means that the total number of marbles is 43.75.
Question: A high school marching band has 35 flute players, If 80 percent of the band members play the flute, then how many members are in the band?
Answer: There are 43.75 members in the band.
How To: The smaller "Part" in this problem is 35 since there are 35 flute players and we are told that they make up 80 percent of the band, so the "Percent" is 80.
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.
35 × 100 = 3500
For step two, we divide that 3500 by the "Percent", which is 80.
3500 divided by 80 equals 43.75
That means that the total number of band members is 43.75.
Step 1: Let's assume the unknown value is Y
Step 2: First writing it as: 100% / Y = 80% / 35
Step 3: Drop the percentage marks to simplify your calculations: 100 / Y = 80 / 35
Step 4: Multiply both sides by Y to move Y on the right side of the equation: 100 = ( 80 / 35 ) Y
Step 5: Simplifying the right side, we get: 100 = 80 Y
Step 6: Dividing both sides of the equation by 80, we will arrive at 43.75 = Y
This leaves us with our final answer: 35 is 80 percent of 43.75
