QuestionWhich is the scale factor proportion for the enlargement shown?
Not drawn to scale 1x=26\frac{1}{x}=\frac{2}{6} 1x=62\frac{1}{x}=\frac{6}{2} 16=2x\frac{1}{6}=\frac{2}{x} 1 . A Mark this and return Save and Exit

STEP 1

What is this asking? We need to find the correct proportion that represents how the smaller parallelogram was enlarged to the bigger one. Watch out! Make sure you match corresponding sides of the parallelograms correctly!
It's easy to mix them up.

STEP 2

1. Set up the proportion
2. Find the matching sides

STEP 3

We can write the proportion as a fraction: \frac{\mbox{small side}}{\mbox{big side}} = \frac{\mbox{another small side}}{\mbox{another big side}}.
This shows how the sides relate to each other in the enlargement.

STEP 4

Let's pick the side of the small parallelogram with length 11 inch as our **first small side**.

STEP 5

The 11-inch side on the small parallelogram corresponds to the xx-inch side on the big parallelogram.
They are in the same position on both shapes.
So, our **matching big side** is xx inches.

STEP 6

Now, let's pick the other side of the small parallelogram, which is 22 inches long, as our **second small side**.

STEP 7

The 22-inch side on the small parallelogram corresponds to the 66-inch side on the big parallelogram.
So, our **matching big side** is 66 inches.

STEP 8

Now we can plug our chosen sides into the proportion: \frac{\mbox{small side}}{\mbox{big side}} = \frac{\mbox{another small side}}{\mbox{another big side}} becomes 1x=26\frac{1}{x} = \frac{2}{6}.

STEP 9

The correct proportion is 1x=26\frac{1}{x} = \frac{2}{6}.
