Understanding the Basics of Fractions, Decimals, and Percents

Fractions, decimals, and percents are three fundamental concepts in mathematics that are often used interchangeably. However, they have distinct meanings and are used in different contexts. In this article, we will explore the relationship between fractions, decimals, and percents, and provide step-by-step solutions to converting fractions to percents.

What are Fractions?

A fraction is a way of expressing a part of a whole as a ratio of two numbers. It consists of a numerator (the top number) and a denominator (the bottom number). For example, the fraction 3/4 represents three equal parts out of a total of four parts.

What are Decimals?

A decimal is a way of expressing a number as a fraction with a denominator that is a power of 10. It consists of a decimal point and digits that represent the numerator. For example, the decimal 0.75 represents 75/100, which is equivalent to the fraction 3/4.

What are Percents?

A percent is a way of expressing a value as a fraction of 100. It is denoted by the symbol % and is often used to represent a proportion or a percentage. For example, the percent 25% represents 25/100, which is equivalent to the fraction 1/4.

Converting Fractions to Percents

To convert a fraction to a percent, we need to divide the numerator by the denominator and multiply the result by 100. This will give us the equivalent percent value.

23. $\frac{9}{10}$ as a percent

To convert the fraction 9/10 to a percent, we need to divide the numerator (9) by the denominator (10) and multiply the result by 100.

$\frac{9}{10} = 0.9 \times 100 = 90\%$

Therefore, the fraction 9/10 is equivalent to 90%.

24. $\frac{9}{20}$ as a percent

To convert the fraction 9/20 to a percent, we need to divide the numerator (9) by the denominator (20) and multiply the result by 100.

$\frac{9}{20} = 0.45 \times 100 = 45\%$

Therefore, the fraction 9/20 is equivalent to 45%.

25. $\frac{9}{25}$ as a percent

To convert the fraction 9/25 to a percent, we need to divide the numerator (9) by the denominator (25) and multiply the result by 100.

$\frac{9}{25} = 0.36 \times 100 = 36\%$

Therefore, the fraction 9/25 is equivalent to 36%.

26. $\frac{9}{30}$ as a percent

To convert the fraction 9/30 to a percent, we need to divide the numerator (9) by the denominator (30) and multiply the result by 100.

$\frac{9}{30} = 0.3 \times 100 = 30\%$

Therefore, the fraction 9/30 is equivalent to 30%.

Conclusion

In this article, we have explored the relationship between fractions, decimals, and percents, and provided step-by-step solutions to converting fractions to percents. We have seen that fractions can be converted to percents by dividing the numerator by the denominator and multiplying the result by 100. This will give us the equivalent percent value. We have also seen that decimals can be converted to percents by multiplying the decimal value by 100. This will give us the equivalent percent value. By understanding the relationship between fractions, decimals, and percents, we can solve a wide range of mathematical problems and make informed decisions in our daily lives.
