List 3 to 5 ways to reduce friction

Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction
Lubrication is another way to make a surface smoother
Make the object more streamlined
Reduce the forces acting on the surfaces
Reduce the contact between the surfaces.

1.Make the surfaces smoother. Rough surfaces produce more friction and 2.smooth surfaces reduce friction.

 3.Lubrication is another way to make a surface smoother.

4.Make the object more streamlined

 5.Reduce the forces acting on the surfaces.

6.Reduce the contact between the surfaces.

hope this helps ;)
