The test I gave my math class covered everything we'd studied all year—fractions, percentages and portions of whole units. But maybe I could have explained things a little better. To the question “What portion of a foot is six inches?” one student answered, “The toes?”
我給我的數(shù)學課學生的考試題涵蓋了一年之內學到的全部內容:小數(shù)、百分數(shù)、分數(shù)。不過,也許我應該把事情再解釋得更清楚一點。因為對于一道題目“一英尺的幾分之幾等于六英寸?”一個學生的答案是:“腳趾頭?”(foot:腳,英尺)
