Step by action solution for calculating 30 is 15 percent the what number
We currently have our very first value 30 and also the second value 15. Let"s i think the unknown value is Y i m sorry answer us will uncover out.
You are watching: 30 is 15 percent of what number
As we have all the compelled values us need, currently we deserve to put castle in a simple mathematical formula as below:
STEP 130 = 15% × Y
STEP 230 = 15/100× Y
Multiplying both sides by 100 and dividing both sides of the equation by 15 we will arrive at:
STEP 3Y = 30 × 100/15
STEP 4Y = 30 × 100 ÷ 15
STEP 5Y = 200
Finally, we have found the worth of Y which is 200 and also that is our answer.
You can easily calculate 30 is 15 percent the what number through using any kind of regular calculator, simply get in 30 × 100 ÷ 15 and you will get your answer which is 200

Sample questions, answers, and how to
Question: her friend has actually a bag the marbles, and also he tells you the 15 percent of the marbles are red. If there room 30 red marbles. How many marbles walk he have actually altogether?
Answer: 200 marbles.

So, that method that it have to be the full that"s missing. Right here is the means to number out what the total is:
Part/Total = Percent/100
By making use of a basic algebra we have the right to re-arrange ours Percent equation like this:
Part × 100/Percent = Total
If us take the "Part" and multiply it by 100, and then we divide that by the "Percent", us will get the "Total".
Let"s try it out on our problem about the marbles, that"s very straightforward and it"s just two steps! We understand that the "Part" (red marbles) is 30.
So step one is to simply multiply that part by 100.
30 × 100 = 3000

Another action by step method
Let"s i think the unknown worth is Y
First creating it as: 100% / Y = 15% / 30
Drop the portion marks to simplify your calculations: 100 / Y = 15 / 30
Multiply both political parties by Y to move Y on the best side that the equation: 100 = ( 15 / 30 ) Y
