No need to feel dumb! I'll help you solve the equation.
To add fractions, we need to find a common denominator. In this case, the common denominator is 14.
Converting the whole number 12 to a fraction with a denominator of 14, we have:
12 = (12 * 14) / 14 = 168 / 14
Now, we can rewrite the equation:
168/14 + 3/14 = ?
Adding the numerators, we get:
(168 + 3) / 14 = 171 / 14
Therefore, 12/7 + 3/14 equals 171/14.
