五年级10月,我们将学习“小数除法”和“观察物体”这两个单元的内容。在“小数除法”这个单元中,我们可以利用以下四步进行计算小数除法:(1)转化。根据商不变的性质将除数转化为整数,除数的小数点向右移动几位,被除数的小数点也要向右移动几位,位数不够时用“0”补足。(2)计算。用整数除法的计算法则进行计算,如果除到被除数的末尾仍有余数,就在余数末尾添“0”继续除。(3)对齐。计算小数除法时,商的小数点和被除数
Fifth grade in October, we will learn the content of the two units of “decimal division” and “observation object.” In the “decimal division ” this unit, we can use the following four steps to calculate the decimal division: (1) conversion. According to the invariable nature of the divisor is converted to an integer, the divisor of the decimal point to the right a few, the decimal point to be moved to the right a few, not enough when the number of “0 ” make up. (2) calculation. Calculate by the rule of integer division, if there is still a remainder except the end of the dividend, add “0” to the end of the remainder to continue. (3) Align. When calculating fractional division, the quotient of the decimal point and the dividend
