括号-16又3/4减去括号-10又1/4减去括号正一又1/2

解: (-16又3/4)-(-10又1/4)-(+1又1/2)

=-16又3/4+10又1/4-1又1/2

=(-16+10-1)+(-3/4+1/4-1/2)

=-7+(-2/4-1/2)

=-7+(-1/2-1/2)

=-7-1

=-8

1/3括号x减四括号加3/4x等于3/2

1/3*（x-4）+3/4*x=3/2
1/3*x-4/3+3/4*x=3/2
13/12*x=17/6
x=34/13

中括号5/8减括号1/2加1/3乘以，3/4中，括号除16/23

【5/8-（1/2+1/3）×3/4】÷16/23

=0÷16/23
=0
