pokemon23 · Answer

wouldn't it be -20 and decrease

anonymous · Answer

No because you have centimeters and Inches.. You have to either change 12 centimeters to inches or change 15 inches to centimeters first

pokemon23 · Answer

isn't the same way to solve this question as the last one?

anonymous · Answer

Im changing the 15 inches to centimeters because its a nicer number.. So now you have $$12 cm \space  \space 38.1cm$$

anonymous · Answer

So now you do $$Percent \space Change = \frac{38.1 - 12}{12} x 100$$
