(5%-i)*( 100-108.11)=(5%-4% )*(100-104)(5%-i)=(5%-4% )*(100-104)/( 100-108.11)i=5%-(5%-4% )*(100-104)/( 100-108.11)=5%-1%*(-4)/(-8.11)=4.51% 這道題到了后面=5%-10%*(-4)/(-8.11)就不懂怎么算了,老師能一步步列等式出來嗎?
溫馨提示:如果以上題目與您遇到的情況不符,可直接提問,隨時問隨時答
速問速答你好,0.05-0.01*(-4)/(-8.11)=0.05-0.01*0.4932=0.05-0.0049=0.0451??梢韵葍蓚€負數(shù)相除得正數(shù)。
