Year 4 Math: Unit 4. Fractions-improper fractions- Study Notes , Worksheets and Online Tests

In year 4 math, students may learn about improper fractions, which are fractions where the numerator (the top number) is greater than or equal to the denominator (the bottom number). For example, 7/4, 12/5, and 9/3 are all examples of improper fractions.

An improper fraction can be converted into a mixed number by dividing the numerator by the denominator and writing the remainder as a fraction. For example, the improper fraction 7/4 can be converted into the mixed number 1 3/4.

7/4 = 1 remainder 3

7/4 = 1 + 3/4

This skill can be useful in solving math problems such as comparing fractions, adding and subtracting fractions, and understanding the relationship between mixed numbers and improper fractions.

It is also an important step when working with decimals and fractions, as it allows students to understand the relationship between them and make conversions from one form to the other.

Here is an example of converting a mixed number to an improper fraction in year 4 math:

Example: Convert the mixed number 3 1/2 to an improper fraction.

Solution: To convert a mixed number to an improper fraction, you need to multiply the whole number by the denominator of the fraction, and then add the numerator to the result.

\(3\frac{1}{2}=\frac{(3 \times2 )+1}{2}=\frac{7}{2}\)
so  \(3\frac{1}{2} \) is same as  \(\frac{7}{2}\)

This skill can be useful in solving math problems such as comparing fractions, adding and subtracting fractions, and understanding the relationship between mixed numbers and improper fractions. It can also be useful in some problem that require to change the form of the numbers.

Here is an example of converting an improper fraction to a mixed number in year 4 math:

Example: Convert the improper fraction 8/3 to a mixed number.

Solution: To convert an improper fraction to a mixed number, you need to divide the numerator by the denominator, and write the quotient as the whole number part, and the remainder as the fractional part.

8/3 = 2 remainder 2

So, 8/3 can be written as  \(2\frac{2}{3}\)  which is mixed number.

This skill can be useful in solving math problems such as comparing fractions, adding and subtracting fractions, and understanding the relationship between mixed numbers and improper fractions. It can also be useful in some problem that require to change the form of the numbers.
