"2 500 000 expected visitors" As the number of visitors are based on an estimate, and no one knows how many visitors are coming.

ReplyDelete120 billion yuan. This is estimated. There is no way it is the exact amount.

ReplyDelete16330000 permanent residents in the city.

ReplyDeleteThe person-in-charge cannot possibly count all of the permanent residents in the city and more permanent residents are entering and staying in the city.

the number is 120 billion yuan

ReplyDeletethis is probably a approximate number as

this is a huge number,this is not really important information, and it seems rounded of because of the number of zeroes.

7,000,000 tickets sold for the game. The ticket-seller cannot possibly count every single ticket that he sells, therefore an an approximate number is given.

ReplyDelete'120 billion yuan' as money is usually rounded up when there is a very big amount and when it is not important information

ReplyDelete10,000,000 bicycles used. The government couldn't have count the total number of bicycles

ReplyDelete16330000 permanent residents in the city. There is definitely more than that number of people. Therefore, the number is being rounded off.

ReplyDeleteThe "120 billion yuan".

ReplyDeleteThis sum is probably rounded up as the sum is too big and they probably rounded up the sum.

120 Billion yuan

ReplyDeleteThe amount of money spent is too large to be keep track of hence it is not accurate. The number keep on changing due to unexpected.

"10,000,000 bicycles used" is a phrase that used approximate figure. It is impossible to count the number of bicycles in Beijing-the number will keep increasing every moment.

ReplyDelete198km Train track in Beijing by 2008.

ReplyDeleteThis is the exact figure because it refers to the length of the train track and so it is an exact figure.

2 500 000 visitors is an approximated figure as some visitors might just decided not to go at the last minute. Hence it is approximated.

ReplyDelete16330000 people, as the number of people can change all the time.

ReplyDelete16330000 permanent residents in the city. The number is very big and constantly changing.

ReplyDelete120 billion yuan is number too big to be counted so it is approximated figure

ReplyDelete10 000 000 bicycles.

ReplyDeleteIt is approximate as they could not have had the time to count the exact number of bicycles and the number of bicycles may decrease and increase each day.

120 billion yuan is an approximate number because this amount is too big and the government will usually choose to round up the number.

ReplyDelete16,330,000 permanent residents of the city.

ReplyDeleteIt is a figure that is approximated. as it is impossible to count the number of residents which is too much to count.

120 billion yuan is too much money to be counted and therefore it is an approximate number
