Here is a Percentage Calculator to solve similar calculations such as 50 is 40 percent of what number. You can solve this type of calculation with your values by entering them into the calculator's fields, and click 'Calculate' to get the result and explanation.
We already have our first value 50 and the second value 40. 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 1
50 = 40% × Y
STEP 250 = 40100× Y
Multiplying both sides by 100 and dividing both sides of the equation by 40 we will arrive at:
STEP 3Y = 50 × 10040
STEP 4Y = 50 × 100 ÷ 40
STEP 5Y = 125
Finally, we have found the value of Y which is 125 and that is our answer.
You can easily calculate 50 is 40 percent of what number by using any regular calculator, simply enter 50 × 100 ÷ 40 and you will get your answer which is 125
Question: Your friend has a bag of marbles, and he tells you that 40 percent of the marbles are red. If there are 50 red marbles. How many marbles does he have altogether?
Answer: 125 marbles.
How To: In this problem, we know that the Percent is 40, and we are also told that the Part of the marbles is red, so we know that the Part is 50.
So, that means that it must be the Total that's missing. Here is the way to figure out what the Total is:
PartTotal = Percent100
By using a simple algebra we can re-arrange our Percent equation like this:
Part × 100Percent = 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 50.
So step one is to just multiply that Part by 100.
50 × 100 = 5000
In step two, we take that 5000 and divide it by the "Percent", which we are told is 40.
So, 5000 divided by 40 = 125
And that means that the total number of marbles is 125.
Question: A high school marching band has 50 flute players, If 40 percent of the band members play the flute, then how many members are in the band?
Answer: There are 125 members in the band.
How To: The smaller "Part" in this problem is 50 since there are 50 flute players and we are told that they make up 40 percent of the band, so the "Percent" is 40.
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.
50 × 100 = 5000
For step two, we divide that 5000 by the "Percent", which is 40.
5000 divided by 40 equals 125
That means that the total number of band members is 125.
Step 1: Let's assume the unknown value is Y
Step 2: First writing it as: 100% / Y = 40% / 50
Step 3: Drop the percentage marks to simplify your calculations: 100 / Y = 40 / 50
Step 4: Multiply both sides by Y to move Y on the right side of the equation: 100 = ( 40 / 50 ) Y
Step 5: Simplifying the right side, we get: 100 = 40 Y
Step 6: Dividing both sides of the equation by 40, we will arrive at 125 = Y
This leaves us with our final answer: 50 is 40 percent of 125
