Answer:
[tex]\large\boxed{6\dfrac{3}{4}\ meters=675\ centimeters}[/tex]
Step-by-step explanation:
[tex]PREFIXES\\\\mega\ (M)=10^6\\\\kilo\ (k)=10^3\\\\hecto\ (h)=10^2\\\\deko\ (da)=10\\\\decy\ (d)=10^{-1}=0.01\\\\centi\ (c)=10^{-2}=0.01\\\\mili\ (m)=10^{-3}=0.001\\\\mikro\ (\mu)=10^{-6}=0.000001[/tex]
[tex]1\ m=100\ cm\qquad(1\ meter=100\ centimeters)\\\\\text{Therefore}\\\\6\dfrac{3}{4}\ m=\dfrac{6\cdot4+3}{4}\ m=\dfrac{27}{4}\ m=\dfrac{27}{4}\cdot100\ cm=\dfrac{2700}{4}\ cm=675\ cm[/tex]
