Answer :
Answer:
300
Step-by-step explanation:
621 rounds to 600 because 21 is smaller than 50. 267 round to 300 since 67 is bigger than 50.
600-300=300
I have found the answer by going to the nearest hundred and making 600 and the I rounded 267 up because it is five or more so it will be rounded to 300 and then you subtract 600-300 and the answer will be 300
