You need 3 sticks for every 24 cookies

So the ratio is


(3)/(24)

Let us use the equivalent ratio to solve the question

We need to find how many stickers for 16 cookies


(3)/(24)=(?)/(16)

By using cross multiplication we will find the missing number


3*16=?*24
48=\text{?}*24

Divide both sides by 24 to find ?


\begin{gathered} (48)/(24)=\text{?}*(24)/(24) \\ 2=\text{?} \end{gathered}

The missing number is 2

let us do the second one

we need to find how many cookies for 5 sticks


(3)/(24)=(5)/(?)

Use cross multiplication


3*?=24*5
3*?\text{ =120}

Divide both sides by 3


\begin{gathered} (3)/(3)*?\text{ =}(120)/(3) \\ \text{? =40} \end{gathered}

The missing number is 40
