约分:把一个分数化成同它相等,但分子、分母都比较小的分数,叫约分。例如:(分子分母同时除以2)通分:把异分母分数分别化成和原来分数相等的同分母分数,叫通分。例如:把和通分;(用 3 和 7 的最小公倍数 21 作公分母)7、分数大小的比较 同分母分数大小的比较:分母相同的分数,分子大的分数比较大;异分母分数大小的比较:分母不同的分数,先通分再按照同分母分数比较大小的方法进行比较。8、四则运算的意义和法则和运算。(同整数)分数化小数分母是 10、100、1000的分数化成小数,可以直接去掉分母,看分母中 1 后面有几个零,就在分子中从最后一位起向左数出几位,点上小数点,没有数字的地方补足“0”。例:0.3;2.049 分母不是 10、100、1000的分数化成小数,要用分母去除分子,除不尽的可以根据需要按四舍五入法保留几位小数。例:340.75;5140.357 小数化分数:原来有几位小数,就在1 后面写几个零作分母,把原来的小数去掉小数点作分子,化成分数后能约分的要约分。分数化百分数:通常先把分数化成小数(除不尽时,通常保留三位文档编码:CC4A7N1V10A4 HD10U10Y4O9H9
