You don't usually connect one source of voltage to another source of voltage.
If you connect a 600-volt machine to a 300-volt source, the machine will look
up at you and laugh.
If you connect a 300-volt machine to a 600-volt source, the machine will run
very fast, overheat, produce smoke, fail, and possibly explode, all possibly
within a small fraction of a second.
600-300=300

600
300. 600 divided by 2 = 300.
300 x 2 = 600
300 x 600 = 180,000
300% of 600 = 1,800
300+300=600
The GCF is 300.
N = 200 300% of 200 = 600
300 increased by 600 percent = 2,100
