Today, we are going to multiply mixed numbers by whole numbers.
Have a look at the in focus question below.
What fraction are we multiplying? What is the whole number that we are multiplying?
That’s right. It is 2 and ½ by 3.
Have a look below to see how we can do this.
2 whole ones multiplied by 3 makes 6 so we would have 6 whole ones.
½ x 3 = 3/2 as the denominator stays the same and 1 x 3 = 3
3/2 is an improper fraction which can be made to a mixed fraction.
Do you know what this could be?
That’s right. It would be 1 whole one and ½.
If we now add 6 whole ones and 1 and a half from above, our answer would be 7 and a half.
As money, our answer would be £7.50.
Now have a look at Q2. How can you work out 3 and 2/3 by 6?
What answer did you get?
Have a look at the video below to see how to work it out.
Now using the same method, have a go at the guided practice section.
Then, complete worksheet 18 below which will be sent to you on Seesaw.
