Question

What is 1/2 ÷ 1/9 ??

Answer 1

We need to compute the following division:

`((1)/(2))/((1)/(9))`

By using the sandwhich rule,

we get

`((1)/(2))/((1)/(9))=(9)/(2)`

This result can be expressed in mixed form as:

`(9)/(2)=4(1)/(2)`

or as decimal form

`(9)/(2)=4.5`

Therefore, the answer is:

`\begin{gathered} \text{ Fraction form:}(9)/(2) \\ Mixed\text{ form: 4}(1)/(2) \\ Decimal\text{ form: 4.5} \end{gathered}`
