Some children do not realise that a fraction such as 2/10 can also be written as a decimal i.e. 0.2. In one sentence we have two of the major sticking points in maths, but here we have a maths worksheet which neatly combines the two, showing the equivalence between fractions and decimal fractions.
One way to show this is to use the fraction as a division sum. 2/10 can be seen as 2 divided by 10. Do this on a calculator to get 0.2. Also remember, to divide by ten mentally, just move each digit one place to the right, putting in the decimal point if moving from units to tenths. This page can be found in our year 4 resources.
