[求助]请问"绝对数和比例"的问题怎么表达

AA中,

题目中用升降的比例得出一结论.我想说比例不能说明问题,要知道绝对数才行.

请问这个意思怎么表达?

拿一道这月JJ来说:

AA  110. The following appeared as part of a memorandum from the loan department of the Frostbite National Bank.

“We should not approve the business loan application of the local group that wants to open a franchise outlet for the Kool Kone chain of ice cream parlors. Frostbite is known for its cold winters, and cold weather can mean slow ice cream sales. For example, even though Frostbite is a town of 10,000 people, it has only one ice cream spot — the Frigid Cow. Despite the lack of competition, the Frigid Cow’s net revenues fell by 10 percent last winter.”

Frostbite国家银行的借贷部门的备忘录：
                
我们不应该批准那个希望开一家KK冰激凌连锁店的特许店的本地团体的借贷请求。Frostbite以其寒冷的冬天而闻名，而冷天气意味着冰激凌的销售不利。比如，虽然Frostbite是个有10000人的镇子，它却只有一家冰激凌店Frigid Cow。尽管缺乏竞争，Frigid Cow的净收入去年冬天下降了10％。

proportion

absolute value

晕死，我以为有这个错误的模板呢，看来要自己瞎编一个出来了．

谢谢ＲＩＯ．
