Write the percentage over 100, simplify the fraction, and verify its simplest form.
Example: 75% becomes
75
100
=

-What are some different ways to express parts of a whole?
There are several ways to express parts of a whole. One way is by using fractions, which represent a part of a whole as a ratio of two integers, such as 1/2 or 3/4. Another way is through percentages, which represent a part of a whole as a part per hundred, like 50% or 75%. Decimals are also used to express parts of a whole, such as 0.5 or 0.75. Additionally, ratios can be used to express the relationship between two numbers, indicating how many times one value contains or is contained within the other, like 1:2 or 3:4. Lastly, proportions can express a part in relation to the whole, such as "one out of two" or "three out of four."
-How can someone convert a percentage into a fraction?
To convert a percentage into a fraction, you can follow these steps. First, write the percentage as a fraction with the percentage number as the numerator and 100 as the denominator. For instance, 75% becomes 75/100. Next, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD). In the case of 75/100, the GCD is 25. Finally, divide the numerator and the denominator by the GCD to get the simplified fraction. For 75/100, you divide both by 25 to get 3/4. Therefore, 75% as a fraction is 3/4.
The fraction 3/4 represents a part of a whole, with 3 as the numerator and 4 as the denominator.
In the fraction 5/8, the numerator, which is 5, indicates the number of parts considered, while the denominator, 8, represents the total number of equal parts.
Understanding the relationship between the numerator and the denominator is crucial in grasping the concept of fractions in mathematics.
What are some different ways to express parts of a whole?
Answer: Parts of a whole can be expressed in several ways, including:
Fractions: Representing parts of a whole number, such as
1/2
, 3/4
, or 5/8
.
Percentages: Indicating parts per hundred, like 50%, 75%, or 62.5%.
Decimals: Showing parts in a base-10 system, for instance, 0.5, 0.75, or 0.625.
Ratios: Comparing two quantities, such as 1:2, 3:4, or 5:8.
Proportions: Equations that state two ratios are equal, for example,
1/2=2/4

1. Ways to Express Parts of a Whole:
- Fractions: Parts of a whole expressed with a numerator and a denominator, like \( \frac{1}{2} \).
- Percentages: Parts per hundred, like 50%.
- Ratios: A comparison between two numbers, like 1:2.
- Decimals: Parts of a whole expressed in decimal form, like 0.5.
2. Converting a Percentage into a Fraction:
