I have got 45 answers on the 19 eggs.

I will post my work in the box after Easter.

I have just worked 9 eggs it was a lot easier than the 19 eggs.

I found 10 answers.

Did the Easter Bunny bring this one? Mrs M

I have worked out that there is a pattern between the answers!

E.g:

If b.1 lays 1 egg there are 9 ways.

If b.1 lays 3 eggs there are 8 ways.

If b.1 lays 5 eggs there are 7 ways.

2 of the birds laid 9 eggs and 1laid 7 eggs.

1bird laid 1 egg, the second bird laid 3 eggs and the third bird laid 15 eggs.

13+5+1=19

9+5+5=19

7+7+5=19

17+1+1=19

11+5+3=19

15+3+1=19

7+3+9=19

If they laid 9 bird eggs between them

3+3+3=9

7+1+1=9

5+3+1=9

well this challenge is quite hard but i will have a go.I am remembering my learning habbits x

Well most birds lay 2 or 3 but if you count up 3×2=6 and 3×3=9 add 9 and 6 equals 15 so the answer is 15. All of them layed 15

13 +5+1=19

5+5+9=19

9+5+5=19

7+3+9=19

3+7+9=19

b.1 layed 6 1/4

b.2 layed 6 1/4

b.3 layed 6 1/4

19 is one whole!

Half of 1/4 is 0.125 which is equal to 2/8 because both one and four are factors of eight!

So one bird has layed less than the other two birds.

So 2/8 (0.125) would be a smaller egg.

The only way all three birds could lay the same was if they all layed 6,1/4 and 0.0625 eggs!

I x’s the 4×2 to get to 8 and 1×2 to get to 2 so 2/8

Half of 0.125 makes the 0.0625 half of 2/8 is 0.125

2/8 is equal to 1/4 not 0.125
