3.29+0.73-2.29+2.27的简便计算3.29+0.73-2.29+2.27的简便计算3.29+0.73-2.29+2.27的简便计算3.29+0.73-2.29+2.27=(3.29-2.
3.29+0.73-2.29+2.27的简便计算
3.29+0.73-2.29+2.27的简便计算
3.29+0.73-2.29+2.27的简便计算
3.29 + 0.73 - 2.29 + 2.27
= ( 3.29 - 2.29 ) + ( 0.73 + 2.27 )
= 1 + 3
= 4
3.29-2.29+(0.73+2.27)=1+3=4
3.29 + 0.73 - 2.29 + 2.27
=(3.29 - 2.29)+(0.73 + 2.27)
= 1 + 3
= 4
你好
3.29+0.73-2.29+2.27
=(3.29-2.29)+(0.73+2.27)
=1+3
=47分之2的分子增加4,要使分数大小不变,分母应该增加多少?7分之2的分子增加4,要使分数大小不变,分母应该增加14
分子增加两倍,分母也增加两倍则分数不变1400米=( )千米填最简分数帮我一下!谢谢1400米=( 7...
