There can only be one reason for that . . . making
something tough out of something easy.
<u>-19 = x - 7</u>

Step-by-step explanation:
The factors for 16 are 1, 2, 4, 8, 16. The two numbers (12and 16) share common factors (1, 2, 4). The greatest of these is 4 and that is the greatest common factor.
Less than one. Neither fraction is greater than a half, so the sum would not exceed 1.
