简便计算~
0.98×1.01-0.98 0.25×0.78×4 3.6×4.7+53×0.36

Answer 1

0.98×1.01-0.98 =0.98*（1.01-1）=0.98*0.01=0.0098
0.25×0.78×4=0.25*4*0.78=1*0.78=0.78
3.6×4.7+5.3×0.36=0.36*（4.7+5.3）=0.36*10=3.6

Answer 2

1. 0.98×1.01-0.98×1 然后 0.98×（1.01-1） 然后0.98×0.01=0.0098
2. 0.25×4×0.78 然后1×0.78=0.78
3. 0.36×0.47+53×0.36 然后0.36×（0.47+53）=

Answer 3

（1）0.98*1.01-0.98=0.98*（1.01-1）=0.0098
（2）0.25*0.78*4=0.25*4*0.78=78
（3）3.6*4.7+53*0.36=36*（0.47+0.53）=36
！！！祝你学业有成！！！

Answer 4

0.98×1.01－0.98=0.98×(1.01－1)=0.98×0.01
0.25×0.78×4=0.25×4×0.78=0.78
3.6×4.7+53×0.36=3.6×4.7+5.3×3.6=3.6×(4.7+5.3)=36

Answer 5

1.0.98x1.01-0.98
=0.98x（1.01-1）
=0.0098
.................打数学的东西好烦啊~~不打了的说~~
第二道0.25*4就等于1然后在乘以0.78就等于0.78
第三道各提出3.6然后4.7就加上了5.3最后等于36

Answer 6

0.0098 0.78 36
