Question

brianna performed a chemistry experiment in which she divided 1/2 of a box of baking soda evenly between 2 bottles. she then added vinegar and water to each bottle to make them bubble up like volcanoes. how much baking soda did she put in each bottle? write your answer as a fraction or as a whole or mixed number.

Explanation:

Step1: Identify the operation

We need to divide $\frac{1}{2}$ of baking soda evenly between 2 bottles. So we use division: $\frac{1}{2} \div 2$.

Step2: Perform the division

Dividing by a number is the same as multiplying by its reciprocal. The reciprocal of 2 is $\frac{1}{2}$. So $\frac{1}{2} \times \frac{1}{2} = \frac{1 \times 1}{2 \times 2} = \frac{1}{4}$.

Answer:

$\frac{1}{4}$
