Adding Fractions: Calculate 1/6 + 2/3 Hour in Food Preparation

The mother spends time preparing both salad and french fries. We need to sum up these two times:

Given the times:

• Salad: $\frac{1}{6}$ hour
• French fries: $\frac{2}{3}$ hour

To add these fractions, we need a common denominator. The denominators are 6 and 3. The least common multiple of 6 and 3 is 6.

Convert $\frac{2}{3}$ to a fraction with a denominator of 6:

$\frac{2}{3} = \frac{2 \times 2}{3 \times 2} = \frac{4}{6}$

Now, add the fractions:

$\frac{1}{6} + \frac{4}{6} = \frac{1 + 4}{6} = \frac{5}{6}$

Therefore, the total time the mother spends preparing food is $\frac{5}{6}$ of an hour.
