1. The problem is to "Add another 7 to the bottom" which likely means to add 7 to the denominator of a fraction or an expression. 2. Suppose we have a fraction $\frac{a}{b}$ and we need to add 7 to the bottom (denominator), the new fraction becomes $\frac{a}{b+7}$. 3. This changes the value of the fraction depending on the original numerator and denominator. 4. For example, if the original fraction was $\frac{3}{4}$, adding 7 to the denominator gives $\frac{3}{4+7} = \frac{3}{11}$. 5. This result is smaller than the original fraction as adding to the denominator decreases the fraction’s value. 6. Without a specific original fraction or number given, the general expression after adding 7 to the bottom is $\frac{a}{b+7}$. 7. Hence, the final expression after adding 7 to the denominator is $\frac{a}{b+7}$.
