0.1 of 25: Understanding the Basics of Fractions
What is 0.1 of 25?
0.1 of 25 is a mathematical expression that can be read as "0.1 times 25" or "0.1 multiplied by 25". To evaluate this expression, we need to understand the concept of fractions and how to multiply a decimal number by an integer.
Fractions and Decimals
In mathematics, a fraction is a way to represent a part of a whole. It consists of a numerator (the top number) and a denominator (the bottom number). For example, the fraction 1/2 represents one half of a whole.
A decimal, on the other hand, is a way to represent a fraction in a more convenient form. It is a number that has a fractional part, separated from the whole part by a decimal point. For example, the decimal 0.5 is equivalent to the fraction 1/2.

To evaluate 0.1 of 25, we need to multiply 0.1 by 25. To do this, we can convert 0.1 to a fraction, which is 1/10.
Now, we can multiply 1/10 by 25:
1/10 × 25 = 25/10 = 2.5
So, 0.1 of 25 is equal to 2.5.
Real-World Applications
Understanding fractions and decimals is essential in real-life situations. For example, in cooking, you may need to multiply a recipe by 0.1 to make a smaller batch of cookies. In finance, you may need to calculate the interest on a loan, which involves multiplying a decimal rate by a principal amount.
Conclusion
In conclusion, 0.1 of 25 is a simple mathematical expression that requires an understanding of fractions and decimals. By converting the decimal to a fraction and multiplying it by the integer, we can evaluate the expression to get the answer, 2.5.
