We are going to start the new term with a refresher of an old favourite - how to convert a fraction into a decimal and percentage using division. To do this remember you need to divide the numerator by the denominator and you can do this using short division. The method is explained in the PowerPoint below.
Now try the following challenges.
The first one you have done in class before.
Yesterday we reminded ourselves how to convert a fraction into a decimal using short division. Today we are going to focus on converting a decimal back into a fraction. Before we do this though, I want to go right back to a reminder about decimal place value. This fabulous video shows us how tenths, hundredths and thousandths can be written as fractions and decimals. It is a really good REVISION for us all!
Today we are going to be revising percentages and we are going to start with what is a percentage. Can you remember what 'per cent' means? When we convert a fraction we have to turn that fraction into an equivalent fraction that has a denominator of 100. Can you think why? We can also do the division method that we learnt on Monday. Both methods work. Watch the following 2 videos about percentages by Maths Antics. I think these videos are excellent!
We will finish this week by reminding ourselves how to tackle some percentage problems. Firstly we will look at finding the percentage of an amount.
