Question

Totsakan enlarged the size of a photo to aheight of 18 in. What is the new width if itwas originally 2 in tall and 1 in wide?

Answer 1

Let's begin by identifying key information given to us:

New size: Height = 18 in, Width = ?

Old size: Height = 2 in, Width = 1 in

We will get the width of the new photo by following the explanation below:

`\begin{gathered} 18\colon2=x\colon1 \\ \Rightarrow(18)/(2)=(x)/(1) \\ \text{Cross multiply, we have:} \\ 2\cdot x=18\cdot1\Rightarrow2x=18 \\ 2x=18 \\ \text{Divide both sides by ''2'', we have:} \\ x=(18)/(2)=9 \\ \therefore x=9in \end{gathered}`

Therefore, the width of the enlarged photo is 9 inches
