0.625×(1又3/1+3又6/1)+6/1÷1又5/3%8/3

原式=5/8×(4/3+19/3)+1/6×8/5-3/8 =5/8×(8+19)/6+1/6×8/5-3/8 =5/8×9/2+4/15-3/8 =(45-6)/16+4/15 =39/16+4/15 =(39×15+4×16)/240 =649/240 =2又169/240

0.625×(1又2/3+3又1/6)+1/6÷1又3/5-5/8 =0.625×(5/3+19/6)+1/6÷8/5-5/8 =5/8×(5/3+19/6)+1/6×5/8-5/8 =5/8×(5/3+19/6+1/6-1) =5/8×4 =5/2

=0.625*(5/3+19/6)+1/6 / 8/5-5/8 =5/8*29/6+1/6 *5/8-5/8 =145/48+5/48-5/8 =150/48-5/8 =25/8-5/8 =20/8 =5/2=2.5

4又1/3+(-5又1/6)等于-5/6, 计算过程如下图。

(1/2-1/3)×6÷1/8 =1/6×6÷1/8 =1÷1/8 =8 本题已解答,如果满意 请点击右下角采纳答案

13/16÷(3/8+1/6) =13/16÷13/24 =13/16×24/13 =3/2

原式=(7/3-7/2+35/18)x(7÷7/6) =7x(1/3-1/2+5/18)x6 =7x(1/3x6-1/2x6+5/18x6) =7x(2-3+5/3) =7x2/3 =14/3

(-3)-[(-5)÷3+(1-2又3分之1×0.6)]×3又4分之3 先算括号里面的,在按照先乘除后加减,谁在前先算谁。
