1. For alley 1: Find the correct decimal scaling ratio. Put it into percent and fraction forms.

2. For alley 2: Find the correct percent scaling ratio. Put it into decimal and fraction forms.

3. For alley 3: Find the correct fraction scaling ratio. Put it into decimal and percent forms.

4. Put your solutions in order from largest to smallest.

BONUS: Which of the three scaling ratio forms was hardest/easiest to use? Why? ]]>
