Question

you need 3 sticks of butter for evey 24 cookies you bakecomplete the table using equivalent ratios

Answer 1

You need 3 sticks for every 24 cookies

So the ratio is

$\frac{3}{24}$

Let us use the equivalent ratio to solve the question

We need to find how many stickers for 16 cookies

$\frac{3}{24}=\frac{?}{16}$

By using cross multiplication we will find the missing number

$3\times16=?\times24$$48=\text{?}\times24$

Divide both sides by 24 to find ?

$\begin{gathered} \frac{48}{24}=\text{?}\times\frac{24}{24} \\ 2=\text{?} \end{gathered}$

The missing number is 2

let us do the second one

we need to find how many cookies for 5 sticks

$\frac{3}{24}=\frac{5}{?}$

Use cross multiplication

$3\times?=24\times5$$3\times?\text{ =120}$

Divide both sides by 3

$\begin{gathered} \frac{3}{3}\times?\text{ =}\frac{120}{3} \\ \text{? =40} \end{gathered}$

The missing number is 40
