一、两个小数的大小。方法:比较两个小数的大小,先看整数部分,整数部分大的小数比较大;如果整数部分相同,看十分位,十分位上大的那个小数比较大……例题:比较0.4和0.8的大小。分析:0.4和0.8的整数部分都是0,看十分位,0.4的十分位是4,0.8的十分位是8,4比8小,所以0.4小于0.8。解答:0.4<0.8。二、多个小数的大小。方法:比较多个小数的大小,可以采用横排法进行比较,先看 One, the size of two decimals. Methods: Compare the size of two decimals, look at the integer part, the integer part of the large fractional larger; if the integer part of the same, see the ten bit, ten bit big decimal that larger ... Example: compare the size of 0.4 and 0.8 . Analysis: 0.4 and 0.8 integer part is 0, to see the decile, 0.4 decile 4, 0.8 decile 8,4 to 8 is small, so 0.4 is less than 0.8. Solution: 0.4 <0.8. Second, the size of multiple decimals. Method: compare the size of more than one decimal, you can use horizontal method to compare, look
