Can anyone help with this KS2 homework, it's circle puzzles?

You have 5 overlapping circles, you have to use each of the numbers 1 to 9 once and the totals within each circle must be equal, so you have to decide where to position each of the numbers.

I'm really hoping someone familiar with this will come along, I've no hope of explaining it properly otherwise.

I am assuming that the circles are all in a row thereby giving 9 'spaces' to fill in.
The end circles only have 2 numbers to add together with the middle 3 circles having 3 numbers to add together (where they overlap with the adjacent circle)

Put the biggest numbers ie 8 and 9 in the end circles then it is just a case of trial and error with the other numbers in the circles/overlaps to see if you can get them to add to same total.

If you imagine the line as circle/overlap/circle overlap etc numbers are:
9 2 5 4 6 1 7 3 8 (9 5 6 7 8 are in the main circles 2 4 1 3 are in the over laps)

hope this makes sense!!
