3x / 2 + 1 = 7 / 6 + X

3x / 2 + 1 = 7 / 6 + X


3x / 2 + 1 = 7 / 6 + X
3(3X+1)=7+X
9X+3 =7+X
9X-X =7-3
8X=4
X=0.5



(1) (2) the ratio of two-thirds to six is: if the former is multiplied by three, the latter should be. If both the former and the latter are divided by two, the ratio is


1.4



If 1 / 2 * 3 = 1 / 2 times 1 / 3 times 1 / 4, 1 / 7 * 2 = 1 / 7 times 1 / 8, then 1 / 3 * 3 = () 1 / 2 * 4-1 / 3 * 4 = ()


1/3*3=(1/3×1/4×1/5)=(1/60)
1/2*4-1/3*4=(1/2×1/3*3-1/3*3×1/6)=1/60×(1/2-1/6)=(1/180)
