  1. Bronze;1- 3
    ;1-none

    Silver;1-850 cm, i used a calculator.
    2-412

    Gold; there was 7 tripods and 1 bipods.
    second answer – 5 tripods and 4 bipods

    platinum;372-91=281
    ;627+54=681

  2. Bronze.
    The odd one out is the 17 because it is not in the 4 time table.
    The 12 is the odd one out why because it is not a multiple of 4 group.
    Silver.
    The have 206 I know this because an baby have more bone than an adult
    The whole intestine all tougher is = 157 and I did it in a paper.
    Gold.
    They were 4 Tripods and 3 Bipods.
    But that was not equal.

  3. 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

  4. 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)

  5. Bronze
    17 is the odd one out because it’s not in the 3 times table.
    Number 10 is the odd one out because it’s not in the 4 times table.

    Silver
    The whole intestine is 850 cm.
    The difference between the length of the two intestine is 650cm.
    150
    +700
    850

    150
    -700
    650

    There are 412 bone in two human skeletons, I know this because I added 206 and 206.

  6. 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

  7. 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

  8. 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
    372-91=281
    627+54=741

  9. Bronze
    1. 17 is the odd one out because it is not comes in the 3 times table . 15, 6
    and 3 comes in 3 times table. 3 times 5=15, 3 times 2= 6 , 3 times 1 =3.
    2. 10 is the odd one out because it does not comes in the 3 times table.
    Silver
    * The whole intestine is 850cm long. 700+ 150 = 850cm. The difference between the length of two intestine is 550 cm. 700 – 150 = 550 cm .
    * There are 412 bones in two skeletons. 206 + 206 = 412 bones.
    Gold
    *There were 5 Tripods. 3 X 5 = 15 .
    There were 4 Bipods . 2 x 4 = 8.
    15 + 8 = 23
    *There were 7 Tripods. 3 x 7 = 21
    * There were 1 Bipods. 2 x 1 = 2
    21+ 2 = 23
    Platinum
    372 – 91 = 281
    627 + 54 = 681

  10. Bronze
    17 because it’s not an equal number
    36 because it’s not equal and is not in the times table
    Silver
    150+700=850
    700-150=650
    The difference is that the longer bone is 850 and the smaller is 650
    I know this because I used my bigger number to add and my smaller to subtract
    Gold
    3×3=9
    So there are nine tripods
    2×3=6
    And there are 6 bipods
    Platinum
    372-91=281
    627+54=682

  11. Keyan 3red
    Bronze

    1.Number is 6 the odd one out. This is because it is an even number. The rest are all odd numbers

    2. None are odd

    Silver

    700 + 150 = 850 long

    150-700 = 550 the difference between the 2 intestines.

    206+206 = 412 bones

    7 tripods and 1 biopod or 5 tripods and 4 bipods

    Platinum

    372-91=281

    627+54=681

  12. Bronze
    17 is the odd one out because 15,6 and 3 is in the 3 times tables.
    10 is the odd one out because 24,36,12 are in the 12 times table
    Silver:
    700+150=850cm long intestine.
    Add the 2 together.
    You have to times 206 x 2 and find the answer.
    Gold.

    5 tripods 4 bipods
    5×3=4×2=8 15+8=23

  13. Bronze
    3,15 and 17
    Silver
    The large one is 150 The small one is 700 if you added together it would make 850.
    There are 412 in two skeletons’.

  14. 3 and 17 because 3 will be for one person and 17 will not be equal.
    Non of them are odd.

    Silver
    150+700=850(The whole length of Intestine is 850)
    700-150=550(The difference is of two length of intestines is 550)
    (Two adults will be 412 bones)you can add or multiply it .
    206+206=412
    206×2=412
    2×206=412

    Gold
    Tripods 3×3=9
    23-9=14
    14%2=7
    So Bipods are 7

    Tripods 5
    5×3=15
    23-15=8
    8%2=4
    Bipods 4
    Platinum
    372-91=281.
    627+54=741.
