The position of rational number a.b.c.d. on the number axis is shown in the figure. An axis with 5 points, equally spaced First point for d Second point for c Third point for b Fourth point for 0 Fifth point for a The position of rational number a.b.c.d. on the number axis is shown in the figure. An axis with 5 points at the same distance The first point represents d The second represents c The third represents b The fourth represents 0 The fifth represents a The graph is not up
An axis with five points, equidistant, first point for d, second point for c, third point for b, fourth point for 0, fifth point for a. equidistant, so a-0=0-bb=-a0-b=b-ccc=2b=-2ab-c=c-dd=2c-b=-4a-(-a)=-3a, then (a+b)/b=(-a+a)/(-a)=0(b-c)/(d-b)×ab=[(-a)-(-2a)]/[(-...
