In this activity, we will be learning about mixed numbers and improper fractions.
A mixed number is made up of a whole number and a fraction.
Let's look at the mixed number below:
This is 3 wholes and 2 fifths.
3 wholes are the same as 5 fifths + 5 fifths + 5 fifths = 15 fifths.
15 fifths + 2 fifths = 17 fifths in total.
Have a look at this picture to help you visualise it:
A quick way to work this out is: 3 x 5 + 2 = 17
Can you see how you multiply the whole number (3) by the denominator (5) and then add the numerator (2)?
3 x 5 = 15 + 2 = 17
17/5 is an improper fraction because it is top-heavy.
That means that the top number is bigger than the bottom number.
It is also easy to convert an improper fraction into a mixed number.
Look at the improper fraction below:
We know that there are five fifths in every whole number, so we can convert this into a mixed number if we divide the numerator by the denominator:
22 ÷ 5 = 4 remainder 2.
So, we have 4 whole numbers and 2 fifths left over as the remainder.
We write the remainder as the numerator. This gives us the answer of 4 and 2/5
