Step by step solution for calculating 205 is 2050 percent of what number

We already have our first value 205 and the second value 2050. 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 1205 = 2050% × Y

STEP 2205 = 2050/100× Y

Multiplying both sides by 100 and dividing both sides of the equation by 2050 we will arrive at:

STEP 3Y = 205 × 100/2050

STEP 4Y = 205 × 100 ÷ 2050

STEP 5Y = 10

Finally, we have found the value of Y which is 10 and that is our answer.

You can easily calculate 205 is 2050 percent of what number by using any regular calculator, simply enter 205 × 100 ÷ 2050 and you will get your answer which is 10

Sample questions, answers, and how to

Question: Your friend has a bag of marbles, and he tells you that 2050 percent of the marbles are red. If there are 205 red marbles. How many marbles does he have altogether?

Answer: 10 marbles.

How To: In this problem, we know that the Percent is 2050, and we are also told that the Part of the marbles is red, so we know that the Part is 205.

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 205.

So step one is to just multiply that Part by 100.

205 × 100 = 20500

In step two, we take that 20500 and divide it by the "Percent", which we are told is 2050.

So, 20500 divided by 2050 = 10

And that means that the total number of marbles is 10.


Question: A high school marching band has 205 flute players, If 2050 percent of the band members play the flute, then how many members are in the band?

Answer: There are 10 members in the band.

How To: The smaller "Part" in this problem is 205 since there are 205 flute players and we are told that they make up 2050 percent of the band, so the "Percent" is 2050.

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.

205 × 100 = 20500

For step two, we divide that 20500 by the "Percent", which is 2050.

20500 divided by 2050 equals 10

That means that the total number of band members is 10.

Another step by step method

Step 1: Let's assume the unknown value is Y

Step 2: First writing it as: 100% / Y = 2050% / 205

Step 3: Drop the percentage marks to simplify your calculations: 100 / Y = 2050 / 205

Step 4: Multiply both sides by Y to move Y on the right side of the equation: 100 = ( 2050 / 205 ) Y

Step 5: Simplifying the right side, we get: 100 = 2050 Y

Step 6: Dividing both sides of the equation by 2050, we will arrive at 10 = Y

This leaves us with our final answer: 205 is 2050 percent of 10
