Answer:
203
Explanation:
To solve this question you can calculate percentages. First find what percent 45/100 is. Since 45 is out of 100 the answer is simply 45%. Next find 45% of 450. This can be found by multiplying 450 by 0.45. This gives you the answer of 202.5. Since you cannot have half a student round up to 203 since 5 always rounds up.
