DIY Challenge 4: How far can you go?
If you had cards from 1 to 10, would it be possible to divide them into 3 groups of equal value?
What if you had cards from 1 to 20 or 1 to 100?
What students worked out7
Student 10
Sum of cards from 1 to 10 is 55.
55 is not divisible by 3.
Hence, it is not possible to divide the cards in 3 groups of equal value.Student 4
Correct sir. If we divide 55 by 3, we would get a decimal answer.
Student 1
1 plus numbers to 10=55 and 55/3= 18.3 so therefor we cannot divide numbers 1 to ten in 3 equal groups.
Student 3
not possible for 1 to 10
1 to 20 is possible
but sir there are no cards labeled 11 to 20
Student 6
No sir 1-10 is not possible as it an even number it cant be dived into 3 equal groups.
1-20 cards is also not possibleStudent 2
1-10 is not possible(as 55 cannot be divided by 3)
1-100 is not possible as 5050 cannot be divided by 3
1-20 is possible as 420 is divided by 3Student 5
It’s not possible cause The Sum of cards from 1 to 10 is 55
and 55 is not divisible by 3.
