    1) 15 because 15 is the odd One out
    2) 10 because 10 is the odd one out
    and 10 is in the 10 Times tables

    Silver
    700+150=850 so it’s 850cm long
    700-150=550 so the difference is
    550cm
    Because I started with the longest
    to the shortest

    Gold
    1) It can equal 23 because have 7 trpods and 1 hipod so it equal 23

    Platinum
    1) 372-91=281
    2)627+54=68
    Create your own number
    234-11=223. 129+120=229
    768-10=758. 123+121=244

    Bronze:
    1) 17 is the odd one out because 3, 6 and 15 are apart of the 3 times table.
    2) 10 is the odd one out because it is not in the 3 times table and 12, 24, 36 all are.
    Silver:
    The whole intestine is 850cm long because 700cm + 150cm = 850cm and the difference is 550cm because 700cm – 150cm = 550cm.

      Well done DJ and Jatifor completing the maths challenge.

  3. Welat M.

    6 because all of the other ones are odd.
    10 because it is a odd one and a even like the other ones
    Silver
    850 I know because 700 + 150 = 850
    412 because 200+200 = 400 and 6+6= 12
    Gold
    G
    First one is 10 bipods and 1 tripods because 2 times 10 = 20 and 1 times 3 = 23
    2 finally 3 times 7 = 21 and + 2 = 23

  4. Esa A.

    1.It is 17 because it is not in the three timetables
    2.It is 12 because it is not in the twelve timetables.
    Silver
    1.150+700=850
    2.There are 412 bones in 2 skeletons
    Gold
    1.There are 4 Bipods and 5 Tripods, 4×2=8 and 5×3=15 so 8+15=23
    2.There are 7 Bipods and 3 Tripods, 7×2=14 and 3×3=9 so 14+9=23
    Platinum

  5. Hadiya M.

    Bronze:
    1) 15, 6, 3, 17 The odd one is 17 because if you count in 3s you end up with 18 not 17.
    2) 24,36, 12, 10 The odd one is 10 because it’s not included in the 3 times table.

    Silver:
    1) The intestine all together is 850. The difference is
    150-700=550. I know this because you have to add first then you will no the difference because you just have to take away 150 from 700.
    2) If there were 2 adult skeletons there would be 412 bones in total. I know this because 206+206=412 so 2 adult skeletons would have 412 bones in total.

    Gold:
    1) There could be 5 Tripods and 4 Bipods. There could be 7 Bipods and 3 Tripods.

    Platinum:
    372-91=281

    627+54=681

    My word problem.
    If 372-91=281 would 91-372=281? 🤔
    If you had £627 but the phone costed £681 would I need 54 more of 45 more? 🤔🌟👌🏻

    I have done my working out in my home work book.
    Bronze
    The odd numbers are 27 and 10 because they are not in the 2 times table.

    Silver
    The length of the whole intestine is 850 cm I got this because I added
    700 cm
    +150 cm
    = 850cm
    Which gave me the answer 850 cm

    700cm
    – 150cm
    = 650cm that is the difference between the 2 intestines.

    The odd number out is 17 as its not in the 3 Times table.
    The odd number out is 10 because 10 isn’t in the 10 Times table.

    150 + 700 =850
    700 – 150 =550 difference

      Also 206 +206 =412

    2. Miss Jephcott

      Well done Kitan ⭐️

  9. Sumayyah A.

    The odd number is 17 beacuse in the 3 x table the next number after 15 would be 18.

    The odd number is 10 because in the 3 x table that number should be 9

    150+700=850

    700-150=550
    To work out the diffecnce in legnth between the two intestines I took away 150 from 700 and the answer to work out the difference in length was 550

    206+206=412
    To get this number I added one adult skeleton to another.

    Tripods – 3
    Bipods – 7

    Tripods – 5
    Bipods – 4

  10. Sumaya O.

    1. The odd one out is 17 because 17 is not in the three times tables.
    2. It is 10 because 10 is not a multiple of three .
    Silver
    The answer is 850cm I know this because 150+700=850 and then I add the centermeters and I got 850cm I did it with formal written method .
    The next answer is 412 because 206 +206=412 .

  11. Faris B.

    Silver
    I added the large intestine and the small intestine together to get the total 700 + 150 = 850cm
    To get the difference between the 2 intestines, I took the shortest away from the longest
    700 – 150 = 550cm

    1 skeleton has 206 bones so 2 skeletons will have 412 bones because 206 + 206 = 412

    BRONZE
    17 is the odd one out because if you count the 3 times table 17 is never there
    2 10 is the odd one out because instead of 10 there is a 9 but never 10 in the three times table.
    SilverThe large instine is 150+700 =850
    The difference is if you put 700-150 =850 also
    2A human body has 206 bones if there were two bodies in one that would =412 I now this because 206 +206 would equal 412
    Gold
    There are 3 bidpods and also 4
    Tripods 3×4=12 there are now 2×3=6

    150+700=850
    700-150=550
    I added 150 and 700 to get the answer and then for the second one I did minus it to get the answer.
    206+206=412
    I added them together to get the answer.

    One of the calculations you could have is 12+11=23 or 14+9=23

    150 + 700 = 850.
    150 – 700 = 550 I know this because 100 – 700 = 600 so 50 – 600 = 550. 206 + 206 = 412 I know this because 200 + 200 = 400 ,
    6 + 6 = 12 so 400 + 12 = 412.

    Tommy had 372 sweets then Oliver took 91 sweets away how many did Tommy have left?
    372 – 91 = 281 Tommy has 281 sweets left.
    Jenny had 627 apples in her farm , one of friend came and gave her 54 apples.
    627 + 54 = 681 so now Jenny had 681 apples all together now.

    700 + 150 = 850 so it’s 850cm long.
    700 – 150 = 550 so the difference is 550cm. To work the difference out I started with the longest and took away the shortest length.
