Step 1
You can work it out using the usual fraction division process, or just through what is happening
If you take one third and cut it in half ( same as dividing by 2), then each piece will be 16 (More pieces, therefore they get smaller)
If you take 16 and cut it in half, the pieces get smaller again. Each piece will be 112
13÷4=13÷2÷2=112
A nifty short cut: To divide a fraction in half, either halve the top (if it is even) or double the bottom:
23÷2=13
411÷2=211 pretty obvious if you think about it!!
59÷2=518
78÷2=716
In the same way: To divide a fraction by 3 in half, either divide the by 3 (if possible) or treble the bottom:
611÷=211 share out 6 portions equally.
58÷3=524

What you do is the KCF method. Keep, Change, Flip. You would keep the 13. Then you change the divide sign to a multiply sign.
Then you flip the 4 to 14.
You do that since 14 is the reciprocal of 4
13÷4=13×14
