AnImproper Fraction has a top number larger than (or equal to) the bottom number.
You are watching: 7/4 as a mixed number
It is usually "top-heavy"
See how the top number is bigger than (or equal to) the bottom number? That makes it an Improper Fraction, (but there is nothing wrong about Improper Fractions).
Three Types of Fractions
There are three types of fraction:
A Fraction (such as 7/4) has two numbers:
The top number (the Numerator) is the number of parts we have. The bottom number (the Denominator) is the number of parts the whole is divided into.
|The numerator is less than the denominator|
|Examples: 1/3, 3/4, 2/7|
|The numerator is greater than (or equal to) the denominator|
|Examples: 4/3, 11/4, 7/7|
|A whole number and proper fraction together|
|Examples: 1 1/3, 2 1/4, 16 2/5|
So an improper fraction is a fraction where the top number (numerator) is greater than or equal to the bottom number (denominator): it is top-heavy.
Can be Equal
What about when the numerator is equal to the denominator? For example 4/4 ?
Well it is the same as a whole, but it is written as a fraction, so most people agree it is a type of improper fraction.
Improper Fractions or Mixed Fractions
We can use either an improper fraction or a mixed fraction to show the same amount.
For example 134 = 74, as shown here:
Converting Improper Fractions to Mixed FractionsTo convert an improper fraction to a mixed fraction, follow these steps:
|Divide the numerator by the denominator.Write down the whole number answerThen write down any remainder above the denominator.|
Example: Convert 114 to a mixed fraction.
11 ÷ 4 = 2 with a remainder of 3
Write down the 2 and then write down the remainder (3) above the denominator (4).
That example can be written like this:
Example: Convert 103 to a mixed fraction.
Converting Mixed Fractions to Improper FractionsTo convert a mixed fraction to an improper fraction, follow these steps:
|Multiply the whole number part by the fraction"s denominator.Add that to the numeratorThen write the result on top of the denominator.|
Example: Convert 325 to an improper fraction.

Multiply the whole number part by the denominator:
3 × 5 = 15
Add that to the numerator:
15 + 2 = 17
Then write that result above the denominator:
We can do the numerator in one go:
Example: Convert 219 to an improper fraction.
Are Improper Fractions Bad ?
NO, they aren"t bad!
For mathematics they are actually better than mixed fractions. Because mixed fractions can be confusing when we write them in a formula: should the two parts be added or multiplied?
|What is:||1 + 214 ?|
|Is it:||1 + 2 + 14||= 314 ?|
|Or is it:||1 + 2 × 14||= 112 ?|
|What is:||1 + 94 ?|
|It is:||44 + 94 = 134|
But, for everyday use, people understand mixed fractions better.
Example: It is easier to say "I ate 214 sausages", than "I ate 94 sausages"
