Question

1 whole
there are halves in 1 whole.

Explanation:

Step1: Analyze the fraction relationship

We know that 1 whole is being divided into equal - sized parts of $\frac{1}{2}$.

Step2: Use division operation

To find out how many $\frac{1}{2}$ are in 1, we calculate $1\div\frac{1}{2}$. According to the rule of dividing by a fraction ($a\div\frac{b}{c}=a\times\frac{c}{b}$), $1\div\frac{1}{2}=1\times\frac{2}{1} = 2$.
