解法1:
3.76-39-5又3分之一+68-4.76-2又6分之一+1又二分之一
=3.76-39-16/3+68-4.76-13/6+3/2
=(3.76-4.76-39+68)-(16/3+13/6-3/2)
=(-1-39+68)-(32/6+13/6-9/6)
=(-40+68)-(32+13-9)/6
=28-36/6
=28-6
=22
解法2:
3.76-39-5又3分之一+68-4.76-2又6分之一+1又二分之一
=3.76-39-(5+1/3)+68-4.76-(2+1/6)+(1+1/2)
=68+(3.76+1-4.76)-39-5-2-(1/3+1/6-1/2)
=68-(39+5+2)-(2+1-3)/6
=68-46
=22
