Step-by-step explanation:
To find 10% of a 45% solution, you can use the following calculation:
10% of 45% = (10/100) * 45%
First, convert 10% to decimal by dividing it by 100: 10/100 = 0.10.
Now, multiply 0.10 by 45% (which is also converted to decimal by dividing it by 100):
0.10 * 45% = 0.10 * 0.45 = 0.045
So, 10% of a 45% solution is 0.045 or 4.5%.
