SSSSS [86.1K]

Answer:

$\frac{7}{11}$

Step-by-step explanation:

By lowest terms, it means to simplify. You can do so by dividing the fraction by a common factor, which in this case, is 6:

$\frac{42}{66}$ ÷ $\frac{6}{6}$ =

$\frac{7}{11}$

The fraction $\frac{7}{11}$ cannot be simplified further, so this is the final answer.
