附:

在一个分数里,分子或分母或两者均含有分数。也叫compound fraction.

具体读法没有统一。一般是先读分子部分,再读分母部分,中间加上divided by
例如:
One minus four fifth plus one third divided by two times two third plus one second

为表达清楚,往往在数字前面加上分子和分母,例如:

Numerator one minus four fifth plus one third divided by denominator two times two third plus one second

分子1减5分之4加3分之1除以分母2乘以3分之2加2分之1
