找出下列算式中第二个因数与积的关系
3.5*1.2=4.2 3.5*1.4=4.9 3.5*1.6=5.6 3.5*1.8=6.3 3.5*2.0=6.4
3.2*0.75=2.4 3.2*0.5=1.6 3.2*0.25=0.8 .2*0.125=0.4 3.2*0.0625=0.2优质解答
(1)由3.5×1.2=4.2,3.5×1.4=4.9 ,3.5×1.6=5.6, 3.5×1.8=6.3, 3.5*2.0=7.0因为被乘数是3.5不变,乘数每增加0.2,积相应增加0.7..（2）由3.2×0.75=2. 4 ,3.2×0.5=1.6 ,3.2×0.25=0.8, 3.2×0.12...
3.5*1.2=4.2 3.5*1.4=4.9 3.5*1.6=5.6 3.5*1.8=6.3 3.5*2.0=6.4
3.2*0.75=2.4 3.2*0.5=1.6 3.2*0.25=0.8 .2*0.125=0.4 3.2*0.0625=0.2
