"…… We are not about to enter the Information Age but instead are rather well into it." Presen predictions are that by 1990, about thirty million jobs in the United States, or about thirty percent of the job market, will be computer-related.
问题 In 1990, the number of jobs having nothing to do with computers in the United States will be reduced to
A) 79 million
B) 30 million
C) 70 million
D) 100 million
我算法是30除以1／3再减去30得到60
答案选C，别告诉我是选最接近的
问题 In 1990, the number of jobs having nothing to do with computers in the United States will be reduced to

C) 70 million
D) 100 million
我算法是30除以1／3再减去30得到60
答案选C，别告诉我是选最接近的
thirty percent,应该是30%.不是1/3.
因此: 30除以30%再减去30得到70.
C. thirty percent 是百分之30.。
所以应该用 30million除以 百分之三十
再减去30 million
thirty million jobs in the United States, or about thirty percent of the job market, will be computer-related
百分之三十于电脑有关，就是70%于电脑无关了
应该这样计算
about thirty million jobs in the United States, or about thirty percent
这里其实是讲同一个数字，意思是“30 million（三千万）”或者（这里表示“也就是”的意思）“百分之三十”的工作是与电脑有关的
所以与电脑无关的工作占百分之七十，也就是70 million（七千万）了
about thirty million jobs in the United States, or about thirty percent of the job market, will be computer-related.
美国约三千万工作,或者约百分之三十的工作市场将于计算机有关.
逻辑分析: 约三千万=约百分之三十于计算机有关
那减去与计算机有关的工作就是C 七千万.
