分、小数加法的运算,一般地说,如果分数能化成有限小数,把分数化成小数再计算,比较简便;如果分数不能化有限小数,就把小数化分数再去计算.但是,后一种情形的算法,一般说来都比较麻烦,很费时间.如果改用整数加分数的方法运算,情况就大不一样了.例如 Generally speaking, if the scores can be turned into finite decimals, it can be easier to divide the scores into decimals and recalculate them. If the scores can not be converted into finite decimals, the fractional scores can be calculated again. However, in the latter case Of the algorithm, in general, are more troublesome, it takes time .If you use the integer plus score method operation, the situation is quite different. For example
