Question

What is 1/2 ÷ 1/9 ??

Answer 1

We need to compute the following division:

$\frac{\frac{1}{2}}{\frac{1}{9}}$

By using the sandwhich rule,

we get

$\frac{\frac{1}{2}}{\frac{1}{9}}=\frac{9}{2}$

This result can be expressed in mixed form as:

$\frac{9}{2}=4\frac{1}{2}$

or as decimal form

$\frac{9}{2}=4.5$

Therefore, the answer is:

$\begin{gathered} \text{ Fraction form:}\frac{9}{2} \\ Mixed\text{ form: 4}\frac{1}{2} \\ Decimal\text{ form: 4.5} \end{gathered}$
