2.An art gallery has three collections:modern art,scupture,and photography.If the 24 items which make up the modern art collection represent 25%of the total number of items in the gallery,then the average number of items in each collection is:
a.8 b.24 c.32 d.96 e.288
答
1 d （412.7乘上100的得数精确到百位是：412.7）
2 c （大概的意思是：一个美术馆有三个展区：modern art,scupture,photography,如果modern art展区有24个项目并占美术馆项目总数的25％,那么每个展区平均有多少项目：24/25％*3＝32）
