1/8+3/14+11/14*1/8怎样简便计算,
1/8+3/14+11/14*1/8怎样简便计算,

1/8+3/14+11/14*1/8怎样简便计算,
前面是加还是乘,加就比较麻烦点
=1/8(1+11/14)+3/14
=1/8x25/14+3/14
=1/14X(25/8+3)
=1/14x49/8
=7/16
乘就简单点
1/8*3/14+11/14*1/8
=1/8*(3/14+11/14)
=1/8*1
=1/8

=1/8(1+11/14)+3/14
=1/8x25/14+3/14
=25/112+24/112
=49/112
=7/16

1/8*3/14+11/14*1/8
=1/8*(3/14+11/14)
=1/8*1
=1/8
