50×0.98 =50×(1-0.02) =50×1-50×0.02 =50-1 =49 谢谢,请采纳

1.5*(1-0.02)=1.5-0.03=1.47

原式等于 7.5×(1-0.02) =7.5-0.15 =7.35 所以原式的结果为7.35

57×0.98=57×(1-0.02)=57×1-57×0.02=57-1.14=55.86

8.8×0.98 =8.8x(1-0.02) =8.8x1-8.8x0.02 =8.8-0.176 =8.624 谢谢,请采纳

7.03X0.98的简便计算 7.03x0.98 =7.03x(1-0.02) =7.03x1-7.03x0.02 =7.03-0.1406 =9.8894

3.7×0.98 =3.7×(1-0.02) =3.7×1-3.7×0.02 =3.7-0.074 =3.626

4.5*0.98+9.8*0.55 =4.5*0.98+55*0.98 =(4.5+55)*0.98 =58.31

0.98×4 =(1-0.02)×4 =1×4-0.02×4 =4-0.08 =3.92

98x0.5 =(100-2)x0.5 =100x0.5-2x0.5 =50-1 =49
