Question

Consider the enlargement of the rectangle. Use the proportion to find the missing dimension bod the original rectangle. (Sorry the pic is horrible)

Answer 1

Answer: 12×=12

×=1, this the correct answer :3

Answer 2

Here's the right way:

`(x)/(\frac 3 5) = (20)/(12)`

`x = (20)/(12) \cdot (3)/(5) = 1`

Here's the way they want you to do it:

`(x)/(\frac 3 5) = (20)/(12)`

`12 x = 20 * (3)/(5) = 12 \textrm{ FIRST BOX}`

`x = 12/12 = 1 \textrm{ SECOND BOX}`
