Sagot :
you can add 5 because 24+5= 29 and still being divisible by 5. if you add six you need to regroup
Answer: There are 5 counters that can be added without having to regroup.
Step-by-step explanation:
Since we have given that
Number of counters = 24
We need to add without having to regroup.
It means that we should make it a prime number which does not get divided by any other number except 1 and itself.
so, After 24, there is other numbers that has chances are as follows:
25,26,27,28,29......
But except 29 all the other number can be regroup as they are composite numbers.
But 29 is the nearest prime number after 24.
So, 24+5=29.
Hence, there are 5 counters that can be added without having to regroup.
