What we have to do is to find the largest common divisor of the two numbers: 12 and 30. It must be at least 2, since they're both even, and at least 3 since both are divisible by 3, so that means that it it also must be at least 6 (2*3=6; if they're divisible by 2 and 3, they must be both divisible by 6).
But they have no bigger divisor than this.
So that means that the number of groups will be 6 (both groups can be divided into 6). It will have 2 (12/6=2) newcomers and 5 (30/6=5) advanced swimmers.

Success can be measured in three ways:
1. Patience. You must be patient especially if you are still new to business. There will be a time when your sales are not good.
2. Perseverance. But no matter how hard it is, you must find ways in order for your business to grow.
3. Good customer service. When you achieved successfully in business, it will be reflected back to your customers whether they have been treated well, their wants are answered and they are contented with your product
