Quizplus · Accepted Answer

To add the fractions $\frac{7}{20}$ and $\frac{1}{18}$, first find a common denominator, which is 360 (the least common multiple of 20 and 18). Convert each fraction: $\frac{7}{20} = \frac{7 \times 18}{20 \times 18} = \frac{126}{360}$ and $\frac{1}{18} = \frac{1 \times 20}{18 \times 20} = \frac{20}{360}$. Adding these gives $\frac{126 + 20}{360} = \frac{146}{360}$, which simplifies to $\frac{73}{180}$ after dividing numerator and denominator by 2.
