用简便方法计算题

4.85乘0.17加上0.485乘8.3

Answer 1

4..85乘0.17加上0.485乘8.3
=0.485*10*0.17+0.485*8.3
=0.485*（10*0.17+8.3）
=0.485*（1.7+8.3）
=0.485*10
=4.85

Answer 2

4.85乘0.17加上0.485乘8.3

=0.485乘1.7加上0.485乘8.3
=0.485×(1.7+8.3）
=0.485×10
=4.85

Answer 3

4.85×0.17+0.485×8.3
=4.85×（0.17+0.83）
=4.85×1
=4.85

Answer 4

4.85*0.17+0.485*8.3=4.85*0.17+4.85*0.83=4.85*(0.17+0.83)=4.85*1=4.85.

Answer 5

=0.485*1.7+0.485*83*=0.485*(1.7+8.3)=0.485*10=4.85

Answer 6

4.85x0.17+0.485x8.3=4.85x(0.17+0.83)=4.85x1=4.85
