How to write the sixth question of volume 43 of sixth grade mathematics published by People's Education Press?
(1) Answer: There are tons shipped every day and days needed in the table, which are related quantities.

(2)300* 1=300 150*2=300 100*3=300

75*4=300 60*5=300 50*6=300

300* 1= 150*2= 100*3=75*4=60*5=50*6

(3) A: It means the total amount of goods.
