To find out how many % is 9 of 9.5, you can write it as an equation
9.5 is therefore 105.5% of 9.
Is this the answer to your question?
You are basically finding a weighted average of 9 and 27. Let x be a percentage. 9x + (1-x)27 = 9.5
-18x + 27 = 9.5
-18x = -17.5
x = 17.5/18 which is approximately 97.2%. So approximately 97.2% of 9 and approximately 2.8% of 27
An easier approach will be to use my preferred method of asking: ''How many % is 9 of 9.5?''. When you ask this, you can put the first number in the denominator (up) and the second number in the numerator (down) and write or 94.7%. Percent just means 'per cent' which just means one out of a hundred. 1% is literally the number 0.01.
This works for any pair of numbers. ''How many percent is 27 of 2 9.5?'' or 284%.
