原式=[5/3-(5/8-1/6+7/12)*24]除以(-5)
=[5/3-15+4-14]]除以(-5)
=-70/3除以(-5)
=14/3
先把小括号去掉,这样是为了分数与24相乘之后得到整数,之后再算大括号的,最后再除以-5
原式=(5/3-(5/8)*24-(1/6)*24-(7/12)*24)/(-5)
=(5/3-15-4-14)/(-5)
=74/3/(-5)=-74/15
[5/3-(5/8-1/6+7/12)×24]÷(-5)
= [5/3-(5/8)×24-1/6×24+7/12×24)]÷(-5)
=[5/3-(15-4+14)]÷(-5)
=(5/3-25)×(-1/5)
=5/3×(-1/5)-25×(-1/5)
=-1/3+5
=4又2/3
三分之十四
