When we talk about "15 of 1100," we are referring to a simple mathematical calculation that represents finding a percentage or a part of a whole number. In this case, we want to determine what 15 represents in relation to the number 1100.
Understanding the Calculation
To find out what 15 of 1100 is, we can use the following formula:
[ \text{Part} = \left( \frac{\text{Percentage}}{100} \right) \times \text{Whole} ]
Where:
 Part is what we want to find (in this case, 15% of 1100).
 Percentage is 15.
 Whole is 1100.
Performing the Calculation
Using the formula mentioned above, we can plug in the numbers:
[ \text{Part} = \left( \frac{15}{100} \right) \times 1100 ]
Calculating this stepbystep:

First, convert 15% into a decimal: [ 15 \div 100 = 0.15 ]

Then multiply this decimal by 1100: [ 0.15 \times 1100 = 165 ]
Conclusion
Thus, 15 of 1100 is 165. This means that if you take 15% of 1100, you arrive at the value of 165. This kind of calculation is useful in various applications, including finance, statistics, and everyday math problems. Understanding how to compute percentages is a fundamental skill that aids in better comprehension of many concepts in mathematics.
