Question

4 add the fractions \\(\frac{1}{3} + \frac{1}{18}\\). drag & drop the answer \\(\frac{7}{18}\\) \\(\frac{5}{18}\\) \\(\frac{1}{18}\\) note: use ctrl+d to drag the option via keyboard

Explanation:

Step1: Find a common denominator

The denominators are 3 and 18. The least common denominator is 18. Rewrite $\frac{1}{3}$ with denominator 18: $\frac{1}{3} = \frac{1\times6}{3\times6} = \frac{6}{18}$.

Step2: Add the fractions

Now add $\frac{6}{18} + \frac{1}{18} = \frac{6 + 1}{18} = \frac{7}{18}$.

Answer:

$\frac{7}{18}$ (corresponding to the first option: $\frac{7}{18}$)
