since they are three consecutive numbers, label the first number x, the second x+1, and the third x+2. set up an equation by adding them and setting them equal to 90 as shown below:
Arranging units from smallest to largest: pm, nm, um, mm, cm, dm, m, km.
Individual measurements in terms of 1 meter. 1 x 10^12 pm = 1 m 1 x 10^9 nm = 1m 1 x 10^6 um = 1m 1 x 10^3 mm = 1m 1 x 10^2 cm = 1m 1 x 10^1 dm = 1m 1m = 1m 1 x 10^-3 km <span> = 1m</span>
