Answer:

300 or 3*10^2 The question isn't written so I can narrow the answer down to one. I think 300 is the best answer, but teachers can be weird.

Answer:

300 or 3*10^2 The question isn't written so I can narrow the answer down to one. I think 300 is the best answer, but teachers can be weird.

Explanation:

300: 3 * 10^2

90000: 9 * 10^4

Ratio: Last year / this year

Ratio: 9*10^4/3*10^2

Ratio: 3 * 10^ (4- 2) You are dividing so the powers subtract. The numbers just divide.

Ratio: 3*10^2

Answer: Simply put the answer is 300. 90000 is 300 times larger than 300

I would use 300 as your answer, but your teach might want 3 * 10^2
