STEP 3Y = 28 × 100/80
STEP 4Y = 28 × 100 ÷ 80
STEP 5Y = 35
Finally, we have found the worth of Y i beg your pardon is 35 and that is our answer.

Sample questions, answers, and how to
Question: your friend has actually a bag the marbles, and he tells you that 80 percent that the marbles space red. If there room 28 red marbles. How many marbles go he have altogether?
Answer: 35 marbles.
How To: In this problem, we understand that the Percent is 80, and we are also told that the part of the marbles is red, so we know that the component is 28.
So, that method that it need to be the total that"s missing. Below is the method to figure out what the total is:
Part/Total = Percent/100
By using a simple algebra we have the right to re-arrange our Percent equation choose this:
Part × 100/Percent = Total
If we take the "Part" and multiply that by 100, and also then we division that by the "Percent", us will get the "Total".
Let"s try it the end on our problem about the marbles, that"s very simple and it"s simply two steps! We understand that the "Part" (red marbles) is 28.
So step one is to simply multiply that part by 100.
28 × 100 = 2800
In action two, we take the 2800 and divide it by the "Percent", i m sorry we room told is 80.

Another action by step method
Let"s assume the unknown worth is Y
First composing it as: 100% / Y = 80% / 28
Drop the percent marks to simplify your calculations: 100 / Y = 80 / 28
Multiply both sides by Y to relocate Y on the right side that the equation: 100 = ( 80 / 28 ) Y
