(8分之3+6分之5)x=870

问题描述:

(8分之3+6分之5)x=870

(3/8+5/6)x=870
(9+4*5)/24x=870
(29/24)x=870
x=(870*24)/29
x=30*24=720

(3/8+5/6)x=870
(9/24+20/24)x=870
29/24x=870
x=720

[(9+20)/24]x=870,x=870*24/29=720

(3/8+5/6)x=870
[(3*6+5*8)/(6*8)]x=870
29/24x=870
x=720

(3/8+5/6)x=870
(9/24+20/24)x=870
29/24*x=870
x=870*24/29=720
