It is true that each part of a whole must be the same size when divided into fractions. This ensures that the fractions accurately represent equal portions of the whole, which is essential for understanding fraction concepts and their applications in real-life scenarios.

Among the given options, 1/5 is the smallest fraction. As the denominator increases, the value of the fraction decreases, making it smaller. This demonstrates the relationship between the number of parts and the size of each part—more parts result in smaller fractions.

A unit fraction is defined as a fraction with a numerator of 1, such as 1/5 or 1/3. This concept is crucial in understanding how fractions operate as parts of a whole. By using unit fractions, we can easily find portions of quantities, making them essential in various practical applications, like cooking or dividing resources.

To find one-third of 90, divide 90 by 3, which equals 30. This calculation exemplifies the use of fractions in determining portions of a given quantity, which is important in various contexts, including budgeting and resource allocation.

When 3 chocolate bars are shared among 4 people, each person receives 3/4 of a chocolate bar. This illustrates how fractions are used to represent shared quantities and is an example of practical applications of dividing resources.

The fraction that represents one-quarter of a quantity is 1/4. This fraction is fundamental in many applications, including sharing, dividing, and calculating portions in cooking and other practical scenarios.

If a whole is divided into 12 equal parts, then 5 parts represent the fraction 5/12. This concept emphasizes the importance of fractions in representing parts of a whole in various situations.

To find one-half of 350 grams, you would calculate 350 ÷ 2, which equals 175 grams. This type of calculation is common in cooking and baking, where precise measurements are crucial.

When a whole is divided into 8 equal parts, each part represents 1/8 of the whole. This is because the fraction is calculated by taking 1 (the part) and dividing it by the total number of parts (8). Understanding how to represent parts of a whole through fractions is fundamental in mathematics.

The fraction 3/4 can be represented mathematically as 3 ÷ 4. This shows that it is the division of the numerator (3) by the denominator (4), which provides a clear understanding of how fractions function in terms of division.

Each part of a hexagon divided into four equal parts represents 1/4 of the whole hexagon. This illustrates how shapes can be divided into fractions, emphasizing the importance of equal parts when working with fractions.

To find 1/6 of 24, you divide 24 by 6, which equals 4. This calculation is a practical application of fractions in determining a portion of a quantity, crucial for tasks such as recipe adjustments or sharing items.

Dividing a shape into 10 equal parts means each part represents 1/10 of the whole. This understanding is vital in geometry and in practical applications where equal divisions are required.
