Test: Fractions - Class 4 MCQ

When you subtract a fraction from itself, the result is always 0. For example, if you have 3/5 and subtract 3/5, you get 0. This concept is fundamental in understanding properties of operations with fractions.

If Zainab takes 1 out of 4 equal parts of the pizza, she has taken 1/4, leaving her with 3/4 of the pizza. This illustrates the concept of fractions in real-life sharing scenarios.

When a cake is divided into 8 equal parts and 3 parts are taken, the fraction representing the portion taken is 3/8. This shows that out of the 8 equal slices, 3 have been consumed. Understanding fractions in this way can help in real-life sharing situations.

An improper fraction is one where the numerator is larger than the denominator, such as 7/4. This concept is important in understanding the relationship between different types of fractions, particularly when converting between mixed numbers and improper fractions.

Unlike fractions are those that have different denominators. In this case, 2/5 and 3/6 are unlike fractions because their denominators (5 and 6) are different. Understanding the difference between like and unlike fractions is crucial for performing arithmetic operations accurately.

The fraction representing three equal parts of a whole divided into four equal parts is 3/4. This illustrates the concept of fractions in terms of parts of a whole, which is fundamental in various real-life contexts such as cooking and sharing.

When a chocolate bar is divided into 2 equal pieces, each piece represents 1/2 of the whole. This concept is fundamental in understanding fractions, especially in sharing scenarios.

Fractions that share the same denominator are termed like fractions. An example is 1/4 and 3/4, where both fractions have the denominator of 4. Understanding this classification helps simplify addition and subtraction of fractions.

In a collection of 3 flowers, with 1 red flower, the fraction representing the part of red flowers is 1/3. This demonstrates how fractions can represent parts of a whole in a collection, which is a useful skill in various applications.

The numerator is the top number in a fraction, which indicates how many parts of the whole are being considered. For example, in the fraction 3/4, the numerator is 3, meaning we have three parts of a total of four. Understanding the role of the numerator helps in grasping the concept of fractions as parts of a whole.

The term three-fourths refers to the fraction 3/4, which indicates that three parts out of a total of four equal parts are being considered. This fraction helps in visualizing portions of a whole, commonly used in recipes and sharing scenarios.

Half of a whole is represented by the fraction 1/2, meaning that the whole is divided into two equal parts, and one of those parts is taken. This is a fundamental concept in fractions that applies to many real-world situations, such as sharing food.

The first step in solving any word problem that involves fractions is to identify the fractions involved. Understanding what fractions you are working with allows you to determine the necessary operations, whether they are addition, subtraction, or others.

To check if two fractions are equivalent, you multiply the numerator of the first fraction by the denominator of the second and vice versa. If the products are equal, the fractions are equivalent. For example, checking if 2/4 and 4/8 are equivalent involves confirming that 2 × 8 = 16 and 4 × 4 = 16.

A unit fraction is defined as a fraction where the numerator is 1. In this case, 1/7 is a unit fraction because its numerator is 1. This concept is fundamental in understanding fractions as it helps identify the smallest portions in fraction representation.

When adding like fractions, you simply add the numerators while keeping the denominator the same. Therefore, 3/8 + 2/8 = (3 + 2)/8 = 5/8. This operation is foundational in fraction arithmetic.

The fractions 1/2, 2/4, and 4/8 are all equivalent because they represent the same part of a whole despite having different numerators and denominators. Understanding equivalent fractions is essential for simplifying and comparing fractions.

To add like fractions, you simply add the numerators while keeping the denominator the same. Thus, 2/5 + 1/5 = (2 + 1)/5 = 3/5. This principle is crucial for performing operations with fractions correctly.

To simplify the fraction 4/8, you divide both the numerator and denominator by their greatest common divisor, which is 4. Thus, 4 ÷ 4 = 1 and 8 ÷ 4 = 2, resulting in the simplified fraction 1/2. Simplifying fractions helps in understanding their true value.

To subtract like fractions, you subtract the numerators while keeping the denominator the same. Thus, 5/6 - 1/6 = (5 - 1)/6 = 4/6. This result can also be simplified further to 2/3 if needed.
