Question

divide.
$2 \div \frac{1}{2} = \square$

Explanation:

Step1: Recall division rule for fractions

Dividing by a fraction is equivalent to multiplying by its reciprocal. So, \(a\div\frac{b}{c}=a\times\frac{c}{b}\) (where \(b
eq0, c
eq0\)).

Step2: Apply the rule to the given problem

For \(2\div\frac{1}{2}\), the reciprocal of \(\frac{1}{2}\) is \(2\). So we rewrite the division as multiplication: \(2\times2\).

Step3: Perform the multiplication

\(2\times2 = 4\).

Answer:

\(4\)
