The LCD of 5 and 3 = 15

4/5 = (4*3)/(5*3) = 12/15

2/3 = (2*5)/(3*5) = 10/15

We know 12 > 10 (by definition)

so

12/15 > 10/15

Or

4/5 > 2/3

This is one of very few places in the study of mathematics where a decimal approximation (or exact decimal representation) may be superior to the nice, clean, fractional values shown above.

It's just trivial like this:

0.800 > 0.666..
