use the ruler to answer the questions below

1. $1 \div \frac{1}{2} = $
2. $3 \div \frac{1}{2} = $
3. what calculation did you do each time?

type your response in the box below.

Explanation:

Step1: Apply reciprocal rule for division

$1 \div \frac{1}{2} = 1 \times \frac{2}{1}$

Step2: Multiply to find result

$1 \times 2 = 2$

Step3: Apply reciprocal rule for division

$3 \div \frac{1}{2} = 3 \times \frac{2}{1}$

Step4: Multiply to find result

$3 \times 2 = 6$

Step5: Identify repeated calculation

Each division by $\frac{1}{2}$ uses multiplying by the reciprocal of $\frac{1}{2}$, which is 2.

Answer:

1. $2$
2. $6$
3. Each time, I multiplied the whole number by 2 (the reciprocal of $\frac{1}{2}$) instead of dividing by $\frac{1}{2}$.
