Oh, what a happy little math problem we have here! Let's think about this together. The two numbers we're looking for are 12 and 16. When you add them, you get 28, and when you multiply them, you get 192. Isn't that just a beautiful little mathematical mystery we've solved together?

Multiply the three-digit number by the one's digit, or last digit, of the two-digit number. That is your first part. Now multiply by the second-to-last digit, or ten's digit, and multiply the result by 10. That is your second part. Add the two parts and that is your answer.

You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
First, multiply the original number by 10. Then multiply the original number by 2. Add the two answers that you got and you have just multiplied by 12. For Example: 7x12=(7x10)+(7x2) 70+14 84
