Today, we are going to continue to multiply mixed numbers.

Have a look at the in focus question below.

What is this information telling you?

How many children are there?

If they each had 1 and 2/3 of a cake roll, how much would they have had in total?

Now have a look at the page below which explains how to find out the total.

We know that we need to multiply 1 and 2/3 by 5 children to find out how many were eaten in total.

 1 and 2/3 1 and 2/3 1 and 2/3 1 and 2/3 1 and 2/3

We know that if each child ate 1 whole one that makes 5 whole ones.

Now, we need to find out if each child ate 2/3 what would the total be.

2/3 added together 5 times would be 10/3. The denominator has stayed the same and we have multiplied 2 x 5 to get 10.

So, we know that in total, the children have eaten 5 whole ones and 10/3.

## trim.7EBF3863-4196-4EEF-B0AA-B4E3037F6342.MOV Use your knowledge now from last week and convert 10/3 into a mixed fraction.

Well done if you got the answer 3 and 1/3.

If we now add 5 whole ones and 3 and 1/3 we would get the final answer of 8 and 1/3.

Have a look at the video below to help you with this.

## trim.AB488106-F57D-4388-8194-BDF588E8BA0F.MOV Now, lets have a look at the same example as above but a different method.

We can change the mixed fraction 1 2/3 into an improper fraction by multiplying the whole number of 1 by the denominator (3) then add this to the numerator (2).

This would make 5/3.

## trim.89AE9BCB-CBE1-4CE9-B6E9-6221DFD7E402.MOV ## trim.BC140DCB-EACC-40A2-AE4C-EBBA2CC2A82F.MOV Now, go back to the top and read all that information again and watch the videos to see how the examples work then try the guided practice questions below.

Then complete worksheet 17 below on Seesaw.
