of the 60 animals on a certain farm, 2/3 are either pigs or cows. how many of the animals are cows? 1. the farm has more than twice as many cows as it has pigs. 2. the farm has more than 12 pigs.
选c 我的疑问 (1) the farm has more than twice as many cows as it has pigs. 这个选项的意思是说 牛比猪的数量的两倍还多么? 我的理解是 牛的数量比猪多两倍 也就是牛是猪的三倍 more than twice as many as 是什么意思?我可能是SC做晕菜了。。
