Answer 1

16*1/9-4/9*7/15-16/15*2/9 怎么简便计算

16*1/9-4/9*7/15-16/15*2/9
=16/9(1-2/15)-4/9*7/15
=16/9*13/15-4/9*7/15
=(16*13-4*7)/9*15
=4(52-7)/9*15
=4*45/9*15
=4/3

1又7/9-4/13x1又7/9怎么简便计算

1又7/9-4/13x1又7/9
=1又7/9×（1-4/13）
=16/9×9/13
=16/13
=1又3/13

15/16+（7/16-1/4）÷4/2的简便计算

15/16+（7/16-1/4）÷4/2
=15/16+（7/16-1/4）÷2
=15/16+（7/16-4/16）÷2
=15/16+（3/16）÷2
=15/16+3/32
=30/32+3/32
=33/32或
=1又1/32

2/9一7/16x2/9该怎样简便计算？

2/9x(1-7/16)
=2/9x9/16
=1/8

16/7-15/4x16/9简便计算

祝学习愉快！

(16/897+4/9)\(1/9+4/897)简便计算

(16/897+4/9)\(1/9+4/897)
=[4×(1/9+4/897)]\(1/9+4/897)
=4×[(1/9+4/897)\(1/9+4/897)]
=4×1
=4

2/9加(1/2一2/9)到简便计算怎么算?

2/9+（1/2-2/9）
=2/9-2/9+1/2
=1/2

9/32除以【4/3乘（7/16减1/4）】简便计算怎么做啊？

解: 9/32÷[4/3*(7/16-1/4)]

=9/32÷[4/3*(7/16-4/16)]

=9/32÷[4/3*(3/16)]

=9/32÷(1/4)

=(9/32)  *4

=9/8
