441 is odd, so we can't divide it by 2.
Since the sum of its digits is , which is divisible by 3, we can divide 441 by 3, and we have
Which is still divisible by 3, because . We have
49 is not divisible by 3 anymore, nor by 5 (it doesn't end with 0 or 5).
It is divisible by 7 though, we have
and finally,
So, the factorization of 441 is
Explanation:
Each box contains
The ratio that compares the number of blueberry bagels in one box to the number of onion bagels in one box will be calculated below as
This means that for every one onionbagels in the box, there are 2 blueberry bagels
Part B:
Given that there are 20 blueberry bagels, the number if onion bagels will be calculated below as
Hence,
The final answer is
