5. #### Muhammed K.

15and17 are odd because 17 not in the3 time or 4 time. Silver 1 700 is long a the difference is 150 down 700 is long. 2 206+206=412. I no because I added

6. #### Alinna A.

Bronze
No this in correct because 3 and 17 3 will be for one person and 17 will not be equal non of them are odd.
Sliver
150+700=850(the whole length of intestine is 550 )
700-150=550(the difference is of two length of intestine is 550)

7. #### Bethany P.

8. #### Anish B.

Bronze

1. 17 is an odd one because it is not a multiple of 3.

2. 10 is an odd one out because it is not a multiple of 4.

Silver

-The whole intestine150cm +700cm = 850cm
-The difference between the intestines 700cm-150cm= 550cm
– Two skeletons will have 206+206= 412, we can also double of 206 or do 206×2= 412

Gold
5 tripods will have 5×3= 15 legs or 4 tripods will have 3×3= 9 legs
9 Bipods will have 9×2= 18 legs or 7 Bipods will have 7×4= 14 legs

9. #### Robyn B.

Bronze
1. 6 is the odd number out because it is and even number.
2. 10 is the odd number out because it is not in the 4 times tables.

Sliver
1. 700 + 150 = 850cm long
2. 700 – 150 = 550cm
3. 206 x 2 = 412. 200+200=400. 6+6=12. 400+12=412. 412 bones

10. #### Ahmed K.

Bronze
1)15,17 and 3 because they are not in the 2 time table
2)24,36,10 and 12 are even but 12 is in the 2 and 3 time table
