Learning Focus: Fractions as decimals (Lesson 2 in your pack)

Remember to visit the youtube channel should you need further explanations.

We can write all fractions as decimals- it may sound tricky but is very simple. When given a decimal the first thing we must do is identify the number of decimal places this will determine our denominator. For example if I was given 0.62, it has 2 decimal places and so it out of hundredth  therefore the fraction will be out of 100, 62/100. 

Let us look at another example, if I have 0.83, I have 2 decimal places so my fraction will be out of 100 again, this time 83/100.

If I was given 0.5 I notice there is only one decimal place so my fraction is a 'tenth' and out of 10, 5/10. Using my knowledge of simplifying I can simplify this to 1/2.

There are some common decimal/fraction conversions which you should remember :
