Step by step solution for calculating 70 is 200 percent of what number

We already have our first value 70 and the second value 200. 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 170 = 200% × Y

STEP 270 = 200/100× Y

Multiplying both sides by 100 and dividing both sides of the equation by 200 we will arrive at:

STEP 3Y = 70 × 100/200

STEP 4Y = 70 × 100 ÷ 200

STEP 5Y = 35

Finally, we have found the value of Y which is 35 and that is our answer.

You can easily calculate 70 is 200 percent of what number by using any regular calculator, simply enter 70 × 100 ÷ 200 and you will get your answer which is 35

Sample questions, answers, and how to

Question: Your friend has a bag of marbles, and he tells you that 200 percent of the marbles are red. If there are 70 red marbles. How many marbles does he have altogether?

Answer: 35 marbles.

How To: In this problem, we know that the Percent is 200, and we are also told that the Part of the marbles is red, so we know that the Part is 70.

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 70.

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

70 × 100 = 7000

In step two, we take that 7000 and divide it by the "Percent", which we are told is 200.

So, 7000 divided by 200 = 35

And that means that the total number of marbles is 35.


Question: A high school marching band has 70 flute players, If 200 percent of the band members play the flute, then how many members are in the band?

Answer: There are 35 members in the band.

How To: The smaller "Part" in this problem is 70 since there are 70 flute players and we are told that they make up 200 percent of the band, so the "Percent" is 200.

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.

70 × 100 = 7000

For step two, we divide that 7000 by the "Percent", which is 200.

7000 divided by 200 equals 35

That means that the total number of band members is 35.

Another step by step method

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

Step 2: First writing it as: 100% / Y = 200% / 70

Step 3: Drop the percentage marks to simplify your calculations: 100 / Y = 200 / 70

Step 4: Multiply both sides by Y to move Y on the right side of the equation: 100 = ( 200 / 70 ) Y

Step 5: Simplifying the right side, we get: 100 = 200 Y

Step 6: Dividing both sides of the equation by 200, we will arrive at 35 = Y

This leaves us with our final answer: 70 is 200 percent of 35
