write your answer as a fraction or as a whole or mixed number.

boxes

submit

Explanation:

Step1: Identify the amount to divide

We have $\frac{1}{2}$ of a box of baking soda to divide among 5 bottles.

Step2: Divide the fraction by the number of bottles

To find the amount per bottle, we divide $\frac{1}{2}$ by 5. Dividing by a number is the same as multiplying by its reciprocal, so $\frac{1}{2} \div 5 = \frac{1}{2} \times \frac{1}{5}$.

Step3: Multiply the fractions

Multiplying the numerators and denominators, we get $\frac{1 \times 1}{2 \times 5} = \frac{1}{10}$.

Answer:

$\frac{1}{10}$
