All questions of Fractions and Division for Year 4 Exam
2/4=1/2
because 1/2×2/2=2/4
so answer is option C
Converting 1/3 to a fraction with a denominator of 12 gives you 4/12. Adding 5/12 and 4/12 results in 9/12, which simplifies to 3/4. This process emphasizes the importance of common denominators in addition.
To find the total cost, divide $30 by 2 and then multiply by 5, giving you $75. This method shows how to determine total costs from fractional parts.
Equivalent fractions can represent the same part of a whole, but they are not necessarily whole numbers. Recognizing this helps in understanding fraction operations better.
Dividing 1 liter by 6 gives each container 1/6 of a liter, which is approximately 166.67 milliliters. This division illustrates how fractions help in distributing quantities evenly.
Dividing 9 by 4 gives 2 with a remainder of 1, thus 9/4 can be expressed as 2 1/4. Mixed numbers are useful for representing fractions in a more understandable way.
A unit fraction has a numerator of 1, such as 1/4. Understanding unit fractions is fundamental when dealing with parts of wholes in various applications.
To find 1/6 of 5/6, multiply the two fractions together: (5/6) × (1/6) = 5/36. This demonstrates how fractions can be multiplied to find parts of a given amount.
To calculate 3/10 of $50, you can multiply $50 by 3 and then divide by 10. This results in $15, demonstrating how to apply fractions to real-world monetary situations.
To simplify 6/9, divide both the numerator and the denominator by their greatest common divisor, which is 3, giving you 2/3. Simplifying fractions is important for clarity and efficiency in calculations.
The numerator indicates how many parts of the whole are being considered, while the denominator shows the total number of equal parts into which the whole is divided. This understanding is essential for interpreting fractions correctly.
When you subtract 2/8 from 7/8, you directly subtract the numerators since the denominators are the same, resulting in 5/8. This illustrates the simplicity of fraction subtraction with like denominators.
To add fractions with different denominators, the first step is to find a common denominator, which for 1/5 and 1/10 is 10. This helps in properly aligning the fractions for addition.
To convert 3 1/4 into an improper fraction, multiply the whole number 3 by the denominator 4 and add the numerator 1, resulting in 13/4. This conversion is essential for performing operations with fractions.
To find the total cost, multiply $40 by 8, yielding $320. This method demonstrates how fractions can represent parts of a whole in financial contexts.
An improper fraction has a numerator that is equal to or larger than the denominator, such as 5/3. Understanding this helps in converting to mixed numbers when necessary.
Eating 1/4 of 1/2 pizza means you consume 1/8 of the whole pizza, leaving you with 3/8. This scenario illustrates subtraction of fractions in practical situations.
Dividing $1 by 100 gives $0.01, which is equivalent to 1 cent. This calculation is an example of how fractions operate in financial transactions.
