冀教版数学二年级上册第二单元测试题及答案
第二单元检测卷及答案一、填一填。1.口算240÷60,可以把240看作( )个十,60看作( )个十,结果为( )。2.计算160÷21时,把除数看作( )来试商,除数变( ),商容易偏( ),调商时要调( )一些。3.776÷83的商是( )位数,862÷52的商是( )位数。4.在除法里,被除数和除数同时( )相同的数(0除外),商不变。5.利用( )的规律,可以简化整十、整百的数除以整十数的计算。6.从522里连续减去( )个29,结果是0。7.一个数除以29,商29,没有余数,这个数是( )。8.○÷△=20……19,除数最小是( ),...
